added dStar_crust to top-level install
tov solver

imported solver for tov. needs routine to setup and integrate crust.
edits to tov eqns.
finish TOV eqns, dense output

ready for integertor and testing
NScool_crust_tov compiles
test of tov

integration appears to work.  next step is to recast variables for more
accurate mass differences.
offset in mass, radius implemented

matches previous results to 1.0e-3.
mass-energy density now returned in HZ90 model
internal energy in mass-energy for HZ90
dStar_crust sample output updated

Now reports rho(number density) and mass-energy density
mass-energy density implemented in TOV

Next: storage of crust model, so it can be handed off to thermal
integration.
added starter lib routine for NScool
building controls

initialization and reading of control parameters
storage, initialization for solver

switched to pointers for consistency throughout.
compile of storage, init routines

bug-fix; compilation successful
volume calculated in TOV

This will be useful for computing mean density of a cell.
storage for TOV model

created storage type.  the variable npts should be the zone count, not
the size of the arrays.
testing storage for TOV solver
test of TOV storage completed

appears to work; now to write a routine to build the initial model
create model routine

wrapper to call TOV and store grid information ready for testing.
