buffRealloc1    reallocate a 1D buffer
buffFree1       free a 1D buffer
buffAlloc2      allocate a 2D buffer
buffFree2       free a 2D buffer

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

buffAlloc1:
Input:
n	size of buffer
Returns:
pointer to type memBUFF

buffRealloc1:
Input:
buff	pointer to buffer
n	new size of buffer

buffFree1:
Input:
buff	pointer to buffer

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