/******************************************************************************
 * Class SWMgr manages installed modules for a frontend.
 * SWMgr reads a mods.conf file to discover its information.
 * It then instantiates the correct decendent of SWModule for each
 * module entry in mods.conf
 * The developer may use this class to query what modules are installed
 * and to retrieve an (SWModule *) for any one of these modules
 *
 * SWMgr makes its modules available as an STL Map.
 * The Map definition is typedef'ed as ModMap
 * ModMap consists of: FIRST : string moduleName
 *                     SECOND: SWModule *module
 *
