/** This abstract class has virtual methods for information that varies across applications. The rest of the methods 
  * are called from the application (i.e. cimserver.cpp), and need to be defined by every operating system implementation. 
  * This version will not touch the method names, as it is fairly risky to do so now. However, the goal is to 
  * eventually standardize the interface so we pull out as much OS-specific function as possible from the main cimserver file.
  *
  * Not all operating systems need to fully implement all these methods.  Stick methods which do not apply to
  * your OS in a "No-ops" section at the top.
  * 
  * See PEP#222 for more information.
