BufferChunk ( byte buffer, int index, int length ) : System	Constructor, create a BufferChunk from its constituent parts
BufferChunk ( int size ) : System	Constructor, create a new BufferChunk and allocate a new byte[] to hold the data.

Copy ( byte source ) : byte[]
CopyFrom ( IntPtr source, Int32 alength ) : void
