Test suite has been updated to include a much more robust suite of tools for validating mesh quality and mesh usability (including but not limited to things such as validating that integrating over a sphere provides the correct volume, that the mesh is confirming, and that no elements are inverted)
Stroid can now generate vacuume regions. These are confirming spheres marked with a seperate attribute that solver may then apply arbitrary mappings to. Further, the boundary of this region is also marked with a seperate boundary attrite allowing seperate boundary conditions to easily be applied.
