hypre is required for parallel MFEM usage and hypre requires MPI. Both of these have been added as dependecies. MPI is added as a dependency in the same manner as boost (i.e. with an install script which checks for system installation and provides a way that the user can initiate a system installation). The MPI install script has been incorporated with the mk script. Hypre has been added as a subproject.
Composition can now be placed in either number fraction or mass fraction mode and can (after finalization) convert between them. Subsets of compositions can also be made. Normalization has also been added to finalize. Tests have been added
MFEM is a dependency of our code and we want to build it with our code for portability, here I add a meson subproject which fetches mfem and builds it. Because of some issues with CMake and meson I apply a patch which manually disables running tests and building examples and miniapps in mfem. This is okay as mfem here is not intenteded to be linked against other programs (though it still can be).
