void wpc1Quant(float *x, int n, float error, void *inconf, void *qstate)
void wpc1Dequant(float *x, int n, void *inconf, void *qstate)

wpc1Quant:
Input:
x		array[] for the floats 
n		0 if the signal is transformed, length of signal otherwise
error		percent RMS error tolerable 
inconf		configuration inf

wpc1Dequant:
Output:
qstate		quantization status

Input:
n		0 if transformed data, length of signal otherwise
inconf		configuration info
qstate		quantization status

Output:
x		array[] for the floats 
wpc1Quant:
Notes:
That the rms error in quantization is about error*RMS_amplitude. The 
magic numbers are based on some relationships of the error measure 
and the step size.
