WPCCODING - Routines for in memory coding of the quantized coeffiecients

codeEncoder	encode the quantized coeffiecients into a bit stream	
codeDecoder	decode a bit stream into the quantized coeffiecients

Function Prototypes:
int codeEncoder(void  *inconf, void *qstate, void *obuff, void *interblock)
int codeDecoder(void  *inconf, void *qstate, void *ibuff, void *interblock)

codeEncoder:
Input:
inconf		configuration info
qstate		quantization status
Output:
outbuff		buffer to hold encoded bit stream
interblock	reserved for inter block communication
Return:
 of bytes after coding

codeDecoder:
Input:
inconf		configuration info
ibuff		buffer to hold encoded symbols
interblock	reserved for inter block communication
Output:
qstate		quantization status
Return:
consistency flag, 1 if wpcCompressed data, 0 otherwise
