//#define USE_SharpZipLib
/* * * * *
 * This is an extension of the SimpleJSON framework to provide methods to
 * serialize a JSON object tree into a compact binary format. Optionally the
 * binary stream can be compressed with the SharpZipLib when using the define
 * "USE_SharpZipLib"
 * 
 * Those methods where originally part of the framework but since it's rarely
 * used I've extracted this part into this seperate module file.
 * 
 * You can use the define "SimpleJSON_ExcludeBinary" to selectively disable
 * this extension without the need to remove the file from the project.
 * 
 * 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
