Added a histogram plotting function for plotting a pseudo rate vs. pt

Doing this for l1Muons, horeco with l1muon match, horeco aboce threshold with l1muon match

removed some comments and adjusted indentation with eclipse
Added a PseudoTrigRate histogram for hoRecos above threshold with a L1Muon match
Add a break statement when matching the l1Muons to horecos. Avoids double counting
