Bug reports:

	Lua 5.1, 5.2, or LuaJIT 2.0
	LPeg (Tested with 0.7, 0.8, 0.9, 0.10, 0.12rc2 ... 0.6 mostly works)
	For regressionTest:
		lfs (Tested with 1.4.1)
	For lunit-tests:
		lunit >= 0.4

NOTE: LPeg 0.11 may not work - it crashed during my tests

Lua versions tested recently:
    Lua 5.1.4 + strict + pl.strict
    Lua 5.2.0 + pl.strict
    LuaJIT-2.0.0-beta10 + strict + pl.strict

	All-but tests: MIT-style, See LICENSE for details
	tests/*:       Public Domain / MIT - whichever is least restrictive

Module/Function overview:
	json.encode (callable module referencing json.encode.encode)
	--encode ( value : ANY-valid )

		Takes in a JSON-encodable value and returns the JSON-encoded text
		Valid input types:
			array-like table (spec below)
			'null' - represented by json.util.null
		Table keys (string,number,boolean) are encoded as strings, others are erroneus
		Table values are any valid input-type
		Array-like tables are converted into JSON arrays...
			Position 1 maps to JSON Array position 0
	--isEncodable ( value : ANY )
		Returns a boolean stating whether is is encodeable or not
		NOTE: Tables/arrays are not deeply inspected

	json.decode (callable module referencing json.decode.decode)
	--decode	(data : string, strict : optional boolean)
		Takes in a string of JSON data and converts it into a Lua object
		If 'strict' is set, then the strict JSON rule-set is used

	--printValue (tab : ANY, name : string)
			recursively prints out all object values - if duplicates found, reference printed
			Reference value to represent 'null' in a well-defined way to
			allow for null values to be inserted into an array/table
	--merge (t : table, ... : tables)
			Shallow-merges a sequence of tables onto table t by iterating over each using
			pairs and assigning.
