	CHANGELOG:
	==========

	8/31/2014:
	---------
	* Fixed bug from last update that broke false/true boolean usage. Courtesy of Vasi B.
	* Change postfix increment of iterators in Serialize to prefix, courtesy of Vasi B.
	* More improvements to validity checking of non string/object/array types. Should
		catch even more invalid usage types such as -1jE5, falsee, trueeeeeee
		{"key" : potato} (that should be {"key" : "potato"}), etc. 
	* Switched to strtol and strtod from atof/atoi in Serialize for better error handling.
	* Fix for GCC order of initialization warnings, courtsey of Vasi B.

	8/17/2014:
	----------
	* Better error handling (and bug fixing) for invalid JSON. Previously, something such as:
			{"def": j[{"a": 100}],"abc": 123}
		would result in at best, a crash, and at worst, nothing when this was passed to 
		the Deserialize method. Note that the "j" is invalid in this example. This led
		to further fixes for other invalid syntax:
		- Use of multiple 'e', for example: 1ee4 is not valid 
		- Use of '.' when not preceded by a digit is invalid. For example: .1 is
			incorrect, but 0.1 is fine.
		- Using 'e' when not preceded by a digit. For example, e4 isn't valid but 1e4 is.

		The deserialize method should properly handle these problems and when there's an
		error, it returns a Value object with the NULLVal type. Check this type to see
		if there's an error.

		Issue reported by Imre Pechan.

	7/21/2014:
	----------
	* All asserts removed and replaced with exceptions, as per request from many users.
		Instead of asserting, functions will throw a std::runtime_error with
		appropriate error message.
	* Added versions of the Value::To* functions that take a default parameter.
		In the event of an error (like calling Value::ToInt() when it's type is an Object),
		the default value you specified will be returned. Courtesy of PeterSvP 
	* Fixed type mismatch warning, courtesy of Per Rovegård
	* Initialized some variables in the various Value constructors to defaults for
		better support with full blast g++ warnings, courtesy of Mark Odell.
	* Changed Value::ToString to return a const std::string& instead of std::string
		to avoid unnecessary copying.
	* Improved some commenting
	* Fixed a bug where a capital E for scientific notation numbers wasn't
		recognized, only lowercase e.
	* VASTLY OVERHAULED AND IMPROVED THE README FILE, PLEASE CONSULT IT FOR
		IN DEPTH USAGE AND EXAMPLES.


 	2/8/2014:
 	--------- 
 	MAJOR BUG FIXES, all courtesy of Per Rovegård, Ph.D.
 	* Feature request: HasKey and HasKeys added to Value for convenience and
 		to avoid having to make a temporary object.
 	* Strings should now be properly unescaped. Previously, as an example, the
 		string "\/Date(1390431949211+0100)\/\" would be parsed as
 		\/Date(1390431949211+0100)\/. The string is now properly parsed as
 		/Date(1390431949211+0100)/.
 		As per http://www.json.org the other escape characters including
 		\u+4 hex digits will now be properly unescaped. So for example,
 		\u0061 now becomes "A".
 	* Serialize now supports serializing a toplevel array (which is valid JSON).
 		The parameter it takes is now a Value, but existing code doesn't
 		need to be changed.
 	* Fixed bug with checking for proper opening/closing sequence for braces/brackets.
 		Previously, this code: 
			const char *json = "{\"arr\":[{}}]}";
			auto val = json::Deserialize(json);
		worked fine with no errors. That's a bug. I did a major overhaul so that
 		now improperly formatted pairs will now correctly result in an error.
 	* Made internal deserialize methods static
 
 	1/30/2014:
 	----------
 	* Changed #pragma once to the standard #ifndef header guard style for
 		better compatibility.
 	* Added a [] operator for Value that takes a const char* as an argument
 		to avoid having to explicitly (and annoyingly) cast to std::string.
 		Thus, my_value["asdf"] = "a string" should now work fine.
 		The same has been added to the Object class.
 	* Added non-operator methods of casting a Value to int/string/bool/etc.
 		Implicitly casting a Value to a std::string doesn't work as per C++
 		rules. As such, previously to assign a Value to a std::string you
 		had to do:
 			my_std_string = (std::string)my_value;
 		You can now instead do:
 			my_std_string = my_value.ToString();
 		If you want more information on why this can't be done, please read
 		this topic for more details:
 		http://stackoverflow.com/questions/3518145/c-overloading-conversion-operator-for-custom-type-to-stdstring
 
 	1/27/2014
 	----------
 	* Deserialize will now return a NULLVal Value instance if there was an
 		error instead of asserting. This way you can handle however you want to
 		invalid JSON being passed in. As a top level object must be either an
 		array or an object, a NULL value return indicates an invalid result.
 
 	1/11/2014
 	---------
 	* Major bug fix: Strings containing []{} characters could cause
 		parsing errors under certain conditions. I've just tested
 		the class parsing a 300KB JSON file with all manner of bizarre
 		characters and permutations and it worked, so hopefully this should
 		be the end of "major bug" fixes.
 
 	1/10/2014
 	---------
 	Bug fixes courtesy of Gerry Beauregard:
 	* Pretty big bug: was using wrong string paramter in ::Deserialize
 		and furthermore it wasn't being trimmed. 
 	* Object::HasKeys now casts the return value to avoid compiler warnings.
 	* Slight optimization to the Trim function
 	* Made asserts in ::Deserialize easier to read
 
 	1/9/2014
 	--------
 	* Major bug fix: for JSON strings containing \" (as in, two characters,
 		not the escaped " character), the lib would mess up and not parse
 		correctly.
 	* Major bug fix: I erroneously was assuming that all root JSON types
 		had to be an object. This was an oversight, as a root JSON
 		object can be an array. I have therefore changed the Deserialize
 		method to return a json::Value rather than a json::Object. This
 		will NOT impact any existing code you have, as a json::Value will
 		cast to a json::Object (if it is indeed an object). But for 
 		correctness, you should be using json::Value = Deserialize...
 		The Value type can be checked if it's an array (or any other type),
 		and furthermore can even be accessed with the [] operator for
 		convenience.
 	* I've made the NULL value type set numeric fields to 0 and bool to false.
 		This is for convenience for using the NULL type as a default return
 		value in your code.
 	* asserts added to casting (Gerry Beauregard)
 	* Added method HasKeys to json::Object which will check if all the keys
 		specified are in the object, returning the index of the first key
 		not found or -1 if all found (hoppe).
 
	1/4/2014
	--------
	* Fixed bug where booleans were being parsed as doubles (Gerry Beauregard).

	1/2/2014 v3
	------------
	* More missing headers added for VisualStudio 2012
	* Switched to snprintf instead of sprintf (or sprintf_s in MSVC)

	1/2/2014 v2
	-----------
	* Added yet more missing headers for compiling on GNU and Linux systems
	* Made Deserialize copy the passed in string so it won't mangle it

	1/2/2014
	--------
	* Fixed previous changelog years. Got ahead of myself and marked them
		as 2014 when they were in fact done in 2013.
	* Added const version of [] to Array/Object/Value
	* Removed C++11 requirements, should work with older compilers
		(thanks to Meng Wang for pointing that out)
	* Made ValueMap and ValueVector typedefs in Object/Value public
		so you can actually iterate over the class
	* Added HasKey and HasValue to Object/Array for convenience
		(note this could have been done comparing .find to .end)

	12/29/2013 v2
	-------------
	* Added .size() field to Value. Returns 1 for non Array/Object types,
		otherwise the number of elements contained.
	* Added .find() to Object to search for a key. Returns Object::end()
		if not found, otherwise the Value.
		Example: bool found = my_obj.find("some key") != my_obj.end();
	* Added .find() to Array to search for a value. Just a convenience
		wrapper for std::find(Array::begin(), Array::end(), Value)
	* Added ==, !=, <, >, <=, >= operators to Object/Array/Value.
		For Objects/Arrays, the operators function just like they do for a
		std::map and std::vector, respectively.
	* Added IsNumeric to Value to indicate if it's an int/float/double type.

	12/29/2013
	----------
	* Added the DoubleVal type which stores, you guessed it, double values.
	* Bug fix for floats with an exact integer value. Now, setting any numerical
		field will also set the fields for the other numerical types. So if you
		have obj["value"] = 12, then the int/float/double cast methods will
		return 12/12.0f/12.0. Previously, in the example above, only the int
		value was set, making a cast to float return 0.
	* Bug fix for deserializing JSON strings that contained large integer values.
		Now if the numerical value of a key in a JSON string contains a number
		less than INT_MIN or greater than INT_MAX it will be stored as a double.
		Note that as mentioned above, all numerical fields are set.
	* Should work fine with scientific notation values now.
	
	12/28/2013
	----------

	* Fixed a bug where if there were spaces around values or key names in a JSON
	string passed in to Deserialize, invalid results or asserts would occur.
	(Fix courtesy of Gerry Beauregard)

	* Added method named "Clear()" to Object/Array/Value to reset state

	* Added license to header file for easyness (totally valid word).
