3.0

This is the version submitted to JOSS.

Since the release for the first pyro paper, the code has undergone considerable development, gained a large number of solvers, adopted unit testing through pytest and documentation through sphinx, and a number of new contributors. pyro's functionality can now be accessed directly through a Pyro() class, in addition to the original commandline script interface. This new interface in particular allows for easy use within Jupyter notebooks. We also now use HDF5 for output instead of python's pickle() function. Previously, we used Fortran to speed up some performance-critical portions of the code. These routines could be called by the main python code by first compiling them using f2py. In the new version, we have replaced these Fortran routines by python functions that are compiled at runtime by numba. Consequently, pyro is now written entirely in python.
