Franjcf/hybridPorousInterFoam: First Release

OpenFOAM Solver for Performing Multiphase Simulations on Hybrid-Scale Porous Media.

This solver simulates two-phase flow in porous media that contains two characteristic length scales: a large scale solid-free domain where flow is solved through the Volume-Of-Fluid Method, and a small scale porous domain where flow is solved through two-phase Darcy's Law. Both domains are coupled and are solved simultaneously with a single momentum equation and within a single mesh.

This first version includes:

1) The solver 2) The necessary complimentary libraries 3) Several tutorial cases
