WPC1CODING - routines for encoding the integer symbols in 1D WPC 

wpc1Encoder - encoder
wpc1Decoder - decoder

Function Prototypes:
void wpc1Encoder(void *qstate, int nblock, void *wpc1)
int wpc1Decoder(void *qstate, int nblock, void *wpc1)

wpc1Encoder:
Input:
quant		quantization status
nblock		# of blocks

Output:
wpc1	 	encoded data

wpc1Decoder:
Input:
nblock		# of blocks
wpc1		compressed data	

Output:
quant		quantization status		

Return:		consistency flag, 1 if wpc1Comressed data, 0 otherwise
