Add functions to make models & auxiliary files for running Le Phare with my custom templates (with nebular lines).
In the print_eazy_flux method, allow users to include filters not in the catalog; it will just output -99.0, -99.0 instead.
Add quick plot functions and fix how it reads best-fit QSO template.
Major revision; add a parent class EAZY and PlotEAZY becomes a subclass of EAZY; also add a class MCEAZY to handle Monte Carlo simulations.
