 * Description: This include file contains all the memory
 *              support macros.
 *
 *
 * Table of contents:
 *
 *   Macros:
 *
 *     KS_MEMORY_ALLOCATE()  . . . . . Allocate a block of memory
 *     KS_MEMORY_FREE()  . . . . . . . Free a block of memory
 *
 *
 *  Notes: Why create these macros instead of using the standard
 *         C I/O routines?  I believe that the support
 *         routines will require some user interface work to handle
 *         cases like when we run out of memory.  Standard C memory
 *         routines don't give me the ability to do such processing.
 *
 *         For now, these macros will simply call the C library
 *         routines (malloc and free).  I'm sure this will change
 *         in the future.
