Separate repo for large mesh and plots files

[andrewwinters5000]

As discussed in #46, large files are no longer tracked in the main HOHQMesh repo. However, it would be useful to create a separate HOHQMesh_mesh_examples repo (name pending) that could act as a storage place for the generated mesh files and SEM formatted TecPlot files for the control files persent in HOHQMesh/Examples (and perhaps others).
