DQM Iteration

Combine function of calDisplay and WC_Reader. Functionality now:

python dqmPlots.py nTuple.root <singleEventNumber>

To speed the response up, this saves plots straight to images (no canvas drawing). WC_Reader will still display all events if you give it a single event.

Also included several peak-finding macros (Brian's). Sam's will be incorporated soon to see both versions.
