Re: gROOT->Reset("a")

Never use "gROOT->Reset" inside a named script! This function should only be called at the start of unnamed macros to cleanup
the previous environment, unnamed macros creating variables in the global scope.

In your example, the call to gROOT->Resets wipes out your include statements.
