 * Description
 * -----------
 * allocate memory for an UCArray, clearing each entry

 * each row references a one-dimensional unsigned char array of size width
 *
 * Inputs
 * ------
 *   width
 *   - the width (number of columns) for the UCArray
 *   height
 *   - the height (number of rows) for the UCArray
 * Return Values
 * ------ ------
 *     UCArray - an allocated, clear, UCArray
 *     NULL    - some error occurred (memory allocation failed)
 *
 * Memory allocated (not deallocated)
 * ------ ---------  --- -----
 * the returned UCArray
 * deallocate after using the array using the FreeUCArray procedure
