WBUFFALLOC -  routines to allocate/initialize and free buffers in wavelet
		packet compresson codes

buffAlloc1 - allocate a 1D  buffer of size n and initialize
buffRealloc1 - reallocate a 1D buffer of size to n and set the position 
		to end of buffer if n is less than buff->pos 
buffFree1 - free a 1D buffer
buffAlloc2 - allocate an array[n1] of buffers each with size n2 and initialize
buffFree2 - free a 2d buffer

Function Prototypes:
void *buffAlloc1(int n);
void buffRealloc1(void *inbuff, int n);
void buffFree1(void *inbuff);
void **buffAlloc2(int n1, int n2);
void buffFree2(void **inbuff, int n1)

buffAlloc1:
Input:
n		size of buffer
Returns:
(void *)buff

buffRealloc1:
inbuff		input buffer
n		size of input buffer

buffFree1:
Input:
inbuff		buffer to be freed

buffAlloc2:
Input:
n1		buffer size in fast dimension
n2		buffer size in slow dimension
