Description: Muon Isolation DQM class

NOTE: The static member variable declarations *should* include the key word "static", but 
I haven't found an elegant way to initalize the vectors.  Static primatives (e.g. int, 
float, ...) and simple static objects are easy to initialze.  Outside of the class 
decleration, you would write
    
int MuonIsolationDQM::CONST_INT = 5;
FooType MuonIsolationDQM::CONST_FOOT = Foo(constructor_argument);
    
but you can't do this if you want to, say, initalize a std::vector with a bunch of 
different values.  So, you can't make them static and you have to initialize them using 
a member method.  To keep it consistent, I've just initialized them all in the same 
method, even the simple types.
