Edit inlist_1 &controls to set initial_mass and initial_z.
You can also edit inlist_1 to set particular abundances, etc.
   
The values for initial_mass and initial_z in the other inlists are not used.
Edit them if you are feeling compulsive, but okay to leave them as is.

May want to change xa_central_lower_limit for h1 in inlist_1 according to your starting composition.
Make it about 0.01 less than the max for center h1 mass fraction.

Edit inlist_5 if you'd like to go beyond center C burning.

Edit inlist_2 to inlist_5 as desired to change other parameters such as
choice of winds, mixing, etc.  Just don't be surprised when your changes break things!


note: we use Arnett's heavily damped hydrodynamics scheme until end of he burning
to suppress pulsations and improve numerical convergence.  (use_artificial_v_damping)

also, since the outer envelope will often have large regions with convection velocities that  
are a significant fraction of the sound speed, we include a factor for turbulent pressure
in the momentum equation. (conv_dP_term_factor)

The maximum mass you can do depends on the metallicity -- high z means bigger Fe opacity bump,
and lower mass where get into trouble.
