//
//    I have converted origional fast h.263 encoder library from C to C++ 
//      so that it can be integrated into any windows application easily.
//      I have removed some of unnecessary codes/files from the
//      fast h263 library.Also moved definitions and declarations
//      in their proper .h and .cpp files.
