Merging nuker and hydro codes.
Galaxy class representing milky way from quataert and subclass representing nuker galaxies
Rename hydro.py to galaxy.py
Changing arguments to constructors.
Delete main function in parker.py--this was confusing and never really used as a wrapper.
Further code reorganization.
Fixing unit issue in velocity dispersion method of Nuker galaxy class.
Changed initialization of the params attribute in Galaxy class so that it would not be overwritten for the case of a nuker galaxy.
Modifying some of the docstrings.
Adding jet property calculation to galaxy code.
Moving the initialization of gridded quantities to solve routines
Getting rid of zone class altogether. Fluid variables are represented as numpy arrays contained in galaxy class.
Fixing cfl condition so that crossing time is computed on a cell-by-cell basis.
Reimplementing conservation checks
Call equation of state routine in case isothermal evolution flag is switched on (to reset sound speed everywhere.
Call equation of state routine if adiabatic index or molecular weight are adjusted.
Update of maximum transport speed for grid in equation of state routine. Uncommenting conservation checks.
Fixing some typos in the source function.
Moving initialization of gridded source term, potential, and potential gradient from constructor to separate method.
Call the eos method in isot_off.
