long(64bit) 자료형을 읽고 쓸수 있는 기능과 숫자형 자료형 데이터는 큰따옴표가 안붙도록 수정한 버전입니다.

간단한 테스트에서는 문제가 없었지만 만약 문제가 생길때는 책임지지 않습니다.

필요하심 마구 퍼가셔도 됨둥...

/* * * * *
 * 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 classes and lists / dictionaries
 * - provides easy access to class 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(JSONClass) 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 class 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 class 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.
