First fit to full model code output, B field only

Modify model code to work with f2py, start testing Python f2py wrapper
code
f2py model code works, skeleton code for all fits

Got f2py model code working (play with step size for scipy leastsq)
Test some values from SN 1006 and verified that lmfit is behaving
decently.  Plan out fit approaches (numbers to produce and reproduce)
and add skeleton code for different fits.
