/* CMemoryAccessCommandBase

 * This class is intended to be used by commands that can make use of memory access but don't

 * necessarily require it. By deriving from CMemoryAccessCommandBase instead of CCommandBase,

 * you reduce the number of times "#ifdef FSHELL_MEMORY_ACCESS_SUPPORT" needs sprinkling through

 * your code. The only bits you need to guard are the bits that use iMemAccess and that call 

 * LoadMemoryAccessL (although you could trap that instead if you really wanted). No need to 

 * include memoryaccess.h or close iMemAccess, and you can include this header and derive from

 * this class unconditionally.
