// cIsThread.h
// Interfaces to the cIsThread class representing an OS-independent wrapper for a class that implements a thread.
// This class will eventually suupersede the old cThread class
/*
Usage:
To have a new thread, declare a class descending from cIsClass.
Then override its Execute() method to provide your thread processing.
In the descending class' constructor call the Start() method to start the thread once you're finished with initialization.
