/********************************************************************
* Description: locmem.hh
*   Implements LOCMEM which is a derived class of CMS that serves
*   primarily to provide addresses that match when matching buffer
*   names are passed to the constructor. It is useful in allowing
*   control modules to use the same inteface to communicate as would
*   be required if they were not running in the same process even
*   though to use LOCMEM they must be.
*
