Fix comment in ZFinderPlotter
Add event number field to RooWorkspaces
Add a minimum 20pt cut for all reco electrons.
Move CutLevel to its own interface file
Split configuration into combined and extended

Combined uses selections designed for the combined Electron-Muon
results. Extended uses selections designed for the extended Eta coverage
possible with electrons.
Add Muon Acceptance flag to ZFinder

The "use_muon_acceptance" flag, when set, will make sure that Zs are
only made from a pair of reco electrons that satisfy:
    * pt>30 and |eta|<2.1
    * pt>20 and |eta|<2.4
If it is set to false, then only pt>20 is required for both reco
electrons (as was the case before).

If no reco Z is created for the event, then the event is not used, so no
cuts are required for the trigger or truth Z.
Clean up Muon Acceptance application

HF and NT electrons never pass, so move the check outside the functions
that initialize these electrons and only run them if the flag isn't set.
Add pyroot script to combine workspaces
Begin work on Efficiency Fitting

Unfortunately, this code must be compiled in ROOT.
Update RooFitter.cpp to do unbinned fits

We use a RooBinning object to make the plot pleasing, while still doing
a completely unbinned fit.
Add interface file and overloaded functions

Add an interface file to act as a "map" to easily see all the functions
we currently have defined, as well as to contain several enums and
constants used globally.

Overload RooFitter to take either a file name, or a file handle. The
latter is useful when running interactively in root with opened files
(_file0, _file1, etc.).

Also clean up includes to just those needed to compile.
Add two fits, one before final cut and one after
Add Nicoles updates to RooMerger.C
Add a Zombie File check to RooMerger.C
Rename some variables and add png output
