Slash implements a "wish-full" thinking idea of getting a new mesh, ideally of higher quality, of a geometry discretized by an existing mesh. The idea is to use the mesh to redefine the geometry and then rely on gmsh
In addition to the FEniCS stack (things are tested for version 2019.1.0) also
networkx and gmsh are required.
Put the directory on PYTHONPATH, e.g. source setup.rc for this bash session
