00008  * Useful when you have a relativly small app like mythcommflag that you
00009  * don't want to wrap inside a QObject enheriting class. 
00010  *
00011  * Unfortunattely QT does not allow this class to be templatized for all
00012  * possible parameter types, so manual labor is in order if you need types other
00013  * than the ones I made here
