20.02

Added a C++ header file, actual_network.H, that defines the
network size. This is the start of making making the
microphysics routines available in C++.
regenerated the pynucastro networks with the latest weak rate
formulations from pynucastro.

The burn_t type no longer includes ydot or jac -- this allows
us to optimize the memory access on GPUs (#220)
The original VODE integrator was removed and the Fortran 90
version VODE90 was renamed to VODE. (#221)
The test_react unit tests no longer require a composition inputs
file (xin*). They now create the composition profile at runtime.

Simplified SDC integration now uses the same retry strategy
as the default (non-SDC) integration. (#215)
VODE90 can now participate in the retry strategy that was
previously available to the VODE integrator, where it can
switch to the BS integrator if loosening the tolerances
does not allow the burn to complete. (#201)
The parameter ode_max_steps was made consistent in VODE and
VODE90; in some places it was being ignored. (#214)
The helmholtz EOS was restructured, splitting the different
components into different functions and optimizing the memory
accesses. (#200)
The derivatives with respect to mass fraction (dpdX, dedX, dhdX)
were removed from eos_t and are now available through a new type,
eos_xderivs_t and the composition_derivatives() routine. (#207)
A bug in the screening of the C12+C12 and O16+O16 rates in iso7
was fixed.
The test_eos unit test now outputs all of the variables in the
eos_t type.

VODE90 now works with the simplified SDC time step algorithms,
and the preprocessor option for this SDC was changed to
SIMPLIFIED_SDC (#194)
rprox now works on GPUs
