// cmCtx_t is used to hold application supplied cmRpt_t, cmErr_t and
// other global values for easy distribution throughtout a cm based application.
//
//  Most the libcm components need at least an application supplied cmRpt_t function
//  to initialize their own internal cmErr_t error class.  Likewise classes which
//  use a cmLHeapH_t based internal heap manager require application wide memory 
// manager configuration information.  The cmCtx_t packages this information and
// allows it to be easily distributed.  The applicaton and its constituent objects
// then need only maintain and pass pointers to a single cmCtx_t object to have access to 
// all the global program information.
