//#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.
