 *  pcy17Dec92: Chnaged some defines in ItemCode list
 *  ane22Dec92: Added local bindery address constant
 *  ane23Dec92: Changed defaults for Lan Manager settings
 *  pcy27Dec92: Added some sensor codes
 *  ane05Jan93: Added slave codes
 *  rct01Jan93: Corrected some problems searching, cleaned things up
 *  ane18Jan93: Added roll percentage defaults
 *  rct26Jan93: Added Remove() methods
 *  rct09Feb93: Split out cfg items array (stdcfg.cxx)

 *  ajr11Mar93: Set default pwrchute_dir to /usr/lib/powerchute for unix
 *  tje12Mar93: Removed strDEFAULT_PWRCHUTE_DIR references
 *  tje13Mar93: Made ConfigManager abstract and added IniConfigManager class
 *  pcy09Sep93: Set object status to indicate ini file create failure
 *  rct03Mar94: fixed Get() for NoDefault case
 *  cad04Mar94: added remove and rename for components
 *  ajr09Mar94: Fixed logical check for ErrNO_ERORR and ErrDEFAULT_VALUE_USED
 *  pcy08Apr94: Trim size, use static iterators, dead code removal
 *  ajr28Apr94: Now striping trailing white spaces in the Get....
 *  mwh07Jun94: port for NCR
 *  pav02Jul96: Added Add to handle lists (i.e. - SmartScheduling)
 *  ntf22Aug97: Changed Component::GetItemValue to be more robust.
 *	awm02Oct97: Added a check to see whether the global _theConfigManager already existed before
 *				setting it equal to the config manager being created.  This is to support multiple
 *				config managers within the application
 *				Took out a line which set the global "_theConfigManager" to NULL in the destructor
 *				of the IniConfigManager.  This will have to be done manually when the config manager
 *				is destroyed in the main application.
 *  mholly06Oct98   : Discontinue use of a cache
