-Package spew implements a deep pretty printer for Go data structures to aid in
-debugging.
-
-A quick overview of the additional features spew provides over the built-in
-printing facilities for Go data types are as follows:
-
-	* Pointers are dereferenced and followed
-	* Circular data structures are detected and handled properly
-	* Custom Stringer/error interfaces are optionally invoked, including
-	  on unexported types
-	* Custom types which only implement the Stringer/error interfaces via
-	  a pointer receiver are optionally invoked when passing non-pointer
-	  variables
-	* Byte arrays and slices are dumped like the hexdump -C command which
-	  includes offsets, byte values in hex, and ASCII output (only when using
-	  Dump style)
-
-There are two different approaches spew allows for dumping Go data structures:
-
-	* Dump style which prints with newlines, customizable indentation,
-	  and additional debug information such as types and all pointer addresses
-	  used to indirect to the final value
-	* A custom Formatter interface that integrates cleanly with the standard fmt
-	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
-	  similar to the default %v while providing the additional functionality
-	  outlined above and passing unsupported format verbs such as %x and %q
-	  along to fmt
-
-Quick Start
-
-This section demonstrates how to quickly get started with spew.  See the
-sections below for further details on formatting and configuration options.
-
-To dump a variable with full newlines, indentation, type, and pointer
-information use Dump, Fdump, or Sdump:
-	spew.Dump(myVar1, myVar2, ...)
-	spew.Fdump(someWriter, myVar1, myVar2, ...)
-	str := spew.Sdump(myVar1, myVar2, ...)
-
-Alternatively, if you would prefer to use format strings with a compacted inline
-printing style, use the convenience wrappers Printf, Fprintf, etc with
-%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
-%#+v (adds types and pointer addresses):
-	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-Configuration Options
-
-Configuration of spew is handled by fields in the ConfigState type.  For
-convenience, all of the top-level functions use a global state available
-via the spew.Config global.
-
-It is also possible to create a ConfigState instance that provides methods
-equivalent to the top-level functions.  This allows concurrent configuration
-options.  See the ConfigState documentation for more details.
-
-The following configuration options are available:
-	* Indent
-		String to use for each indentation level for Dump functions.
-		It is a single space by default.  A popular alternative is "\t".
-
-	* MaxDepth
-		Maximum number of levels to descend into nested data structures.
-		There is no limit by default.
-
-	* DisableMethods
-		Disables invocation of error and Stringer interface methods.
-		Method invocation is enabled by default.
-
-	* DisablePointerMethods
-		Disables invocation of error and Stringer interface methods on types
-		which only accept pointer receivers from non-pointer variables.
-		Pointer method invocation is enabled by default.
-
-	* DisablePointerAddresses
-		DisablePointerAddresses specifies whether to disable the printing of
-		pointer addresses. This is useful when diffing data structures in tests.
-
-	* DisableCapacities
-		DisableCapacities specifies whether to disable the printing of
-		capacities for arrays, slices, maps and channels. This is useful when
-		diffing data structures in tests.
-
-	* ContinueOnMethod
-		Enables recursion into types after invoking error and Stringer interface
-		methods. Recursion after method invocation is disabled by default.
-
-	* SortKeys
-		Specifies map keys should be sorted before being printed. Use
-		this to have a more deterministic, diffable output.  Note that
-		only native types (bool, int, uint, floats, uintptr and string)
-		and types which implement error or Stringer interfaces are
-		supported with other types sorted according to the
-		reflect.Value.String() output which guarantees display
-		stability.  Natural map order is used by default.
-
-	* SpewKeys
-		Specifies that, as a last resort attempt, map keys should be
-		spewed to strings and sorted by those strings.  This is only
-		considered if SortKeys is true.
-
-Dump Usage
-
-Simply call spew.Dump with a list of variables you want to dump:
-
-	spew.Dump(myVar1, myVar2, ...)
-
-You may also call spew.Fdump if you would prefer to output to an arbitrary
-io.Writer.  For example, to dump to standard error:
-
-	spew.Fdump(os.Stderr, myVar1, myVar2, ...)
-
-A third option is to call spew.Sdump to get the formatted output as a string:
-
-	str := spew.Sdump(myVar1, myVar2, ...)
-
-Sample Dump Output
-
-See the Dump example for details on the setup of the types and variables being
-shown here.
-
-	(main.Foo) {
-	 unexportedField: (*main.Bar)(0xf84002e210)({
-	  flag: (main.Flag) flagTwo,
-	  data: (uintptr) <nil>
-	 }),
-	 ExportedField: (map[interface {}]interface {}) (len=1) {
-	  (string) (len=3) "one": (bool) true
-	 }
-	}
-
-Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
-command as shown.
-	([]uint8) (len=32 cap=32) {
-	 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
-	 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
-	 00000020  31 32                                             |12|
-	}
-
-Custom Formatter
-
-Spew provides a custom formatter that implements the fmt.Formatter interface
-so that it integrates cleanly with standard fmt package printing functions. The
-formatter is useful for inline printing of smaller data types similar to the
-standard %v format specifier.
-
-The custom formatter only responds to the %v (most compact), %+v (adds pointer
-addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
-combinations.  Any other verbs such as %x and %q will be sent to the the
-standard fmt package for formatting.  In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
-
-Custom Formatter Usage
-
-The simplest way to make use of the spew custom formatter is to call one of the
-convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
-functions have syntax you are most likely already familiar with:
-
-	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-	spew.Println(myVar, myVar2)
-	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-See the Index for the full list convenience functions.
-
-Sample Formatter Output
-
-Double pointer to a uint8:
-	  %v: <**>5
-	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
-	 %#v: (**uint8)5
-	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
-
-Pointer to circular struct with a uint8 field and a pointer to itself:
-	  %v: <*>{1 <*><shown>}
-	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
-	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
-	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
-
-See the Printf example for details on the setup of variables being shown
-here.
-
-Errors
-
-Since it is possible for custom Stringer/error interfaces to panic, spew
-detects them and handles them internally by printing the panic information
-inline with the output.  Since spew is intended to provide deep pretty printing
-capabilities on structures, it intentionally does not return any errors.

-	* Custom Stringer/error interfaces are optionally invoked, including
-	  on unexported types
-	* Custom types which only implement the Stringer/error interfaces via
-	  a pointer receiver are optionally invoked when passing non-pointer
-	  variables
-	* Byte arrays and slices are dumped like the hexdump -C command which
-	  includes offsets, byte values in hex, and ASCII output
-
-The configuration options are controlled by an exported package global,
-spew.Config.  See ConfigState for options documentation.
-
-See Fdump if you would prefer dumping to an arbitrary io.Writer or Sdump to

-NewFormatter returns a custom formatter that satisfies the fmt.Formatter

-
-The custom formatter only responds to the %v (most compact), %+v (adds pointer
-addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
-combinations.  Any other verbs such as %x and %q will be sent to the the
-standard fmt package for formatting.  In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
-

-use of the custom formatter by calling one of the convenience functions such as
-Printf, Println, or Fprintf.

-// SequenceMatcher compares sequence of strings. The basic
-// algorithm predates, and is a little fancier than, an algorithm
-// published in the late 1980's by Ratcliff and Obershelp under the
-// hyperbolic name "gestalt pattern matching".  The basic idea is to find
-// the longest contiguous matching subsequence that contains no "junk"
-// elements (R-O doesn't address junk).  The same idea is then applied
-// recursively to the pieces of the sequences to the left and to the right
-// of the matching subsequence.  This does not yield minimal edit
-// sequences, but does tend to yield matches that "look right" to people.
-//
-// SequenceMatcher tries to compute a "human-friendly diff" between two
-// sequences.  Unlike e.g. UNIX(tm) diff, the fundamental notion is the
-// longest *contiguous* & junk-free matching subsequence.  That's what
-// catches peoples' eyes.  The Windows(tm) windiff has another interesting
-// notion, pairing up elements that appear uniquely in each sequence.
-// That, and the method here, appear to yield more intuitive difference
-// reports than does diff.  This method appears to be the least vulnerable
-// to synching up on blocks of "junk lines", though (like blank lines in
-// ordinary text files, or maybe "<P>" lines in HTML files).  That may be
-// because this is the only method of the 3 that has a *concept* of
-// "junk" <wink>.
-//
-// Timing:  Basic R-O is cubic time worst case and quadratic time expected
-// case.  SequenceMatcher is quadratic time for the worst case and has
-// expected-case behavior dependent in a complicated way on how many
-// elements the sequences have in common; best case time is linear.

-Objx - Go package for dealing with maps, slices, JSON and other data.
-
-Overview
-
-Objx provides the `objx.Map` type, which is a `map[string]interface{}` that exposes
-a powerful `Get` method (among others) that allows you to easily and quickly get
-access to data within the map, without having to worry too much about type assertions,
-missing data, default values etc.
-
-Pattern
-
-Objx uses a preditable pattern to make access data from within `map[string]interface{}` easy.
-Call one of the `objx.` functions to create your `objx.Map` to get going:
-
-    m, err := objx.FromJSON(json)
-
-NOTE: Any methods or functions with the `Must` prefix will panic if something goes wrong,
-the rest will be optimistic and try to figure things out without panicking.
-
-Use `Get` to access the value you're interested in.  You can use dot and array
-notation too:
-
-     m.Get("places[0].latlng")
-
-Once you have sought the `Value` you're interested in, you can use the `Is*` methods to determine its type.
-
-     if m.Get("code").IsStr() { // Your code... }
-
-Or you can just assume the type, and use one of the strong type methods to extract the real value:
-
-   m.Get("code").Int()
-
-If there's no value there (or if it's the wrong type) then a default value will be returned,
-or you can be explicit about the default value.
-
-     Get("code").Int(-1)
-
-If you're dealing with a slice of data as a value, Objx provides many useful methods for iterating,
-manipulating and selecting that data.  You can find out more by exploring the index below.
-
-Reading data
-
-A simple example of how to use Objx:
-
-   // Use MustFromJSON to make an objx.Map from some JSON
-   m := objx.MustFromJSON(`{"name": "Mat", "age": 30}`)
-
-   // Get the details
-   name := m.Get("name").Str()
-   age := m.Get("age").Int()
-
-   // Get their nickname (or use their name if they don't have one)
-   nickname := m.Get("nickname").Str(name)
-
-Ranging
-
-Since `objx.Map` is a `map[string]interface{}` you can treat it as such.
-For example, to `range` the data, do what you would expect:
-
-    m := objx.MustFromJSON(json)
-    for key, value := range m {
-      // Your code...
-    }
