* A simple JSON Parser / builder
* ------------------------------
*
* It mainly has been written as a simple JSON parser. It can build a JSON string
* from the node-tree, or generate a node tree from any valid JSON string.
*
* If you want to use compression when saving to file / stream / B64 you have to include
* SharpZipLib ( http://www.icsharpcode.net/opensource/sharpziplib/ ) in your project and
* define "USE_SharpZipLib" at the top of the file
*
* Written by Bunny83
* 2012-06-09
*
* Features / attributes:
* - provides strongly typed node clastes and lists / dictionaries
* - provides easy access to clast members / array items / data values
* - the parser ignores data types. Each value is a string.
* - only double quotes (") are used for quoting strings.
* - values and names are not restricted to quoted strings. They simply add up and are trimmed.
* - There are only 3 types: arrays(JSONArray), objects(JSONClast) and values(JSONData)
* - provides "casting" properties to easily convert to / from those types:
* int / float / double / bool
* - provides a common interface for each node so no explicit casting is required.
* - the parser try to avoid errors, but if malformed JSON is parsed the result is undefined
*
*
* 2012-12-17 Update:
* - Added internal JSONLazyCreator clast which simplifies the construction of a JSON tree
* Now you can simple reference any item that doesn't exist yet and it will return a JSONLazyCreator
* The clast determines the required type by it's further use, creates the type and removes itself.
* - Added binary serialization / deserialization.
* - Added support for BZip2 zipped binary format. Requires the SharpZipLib ( http://www.icsharpcode.net/opensource/sharpziplib/ )
* The usage of the SharpZipLib library can be disabled by removing or commenting out the USE_SharpZipLib define at the top
* - The serializer uses different types when it comes to store the values. Since my data values
* are all of type string, the serializer will "try" which format fits best. The order is: int, float, double, bool, string.
* It's not the most efficient way but for a moderate amount of data it should work on all platforms.
