[Gmsh] Some nice surface meshes

I've recently been using the remeshing stuff in gmsh to mesh isosurfaces of voxel images.  An initial triangulation of the surface is extracted using the marching tetrahedra algorithm.  These triangulations are conforming but the element quality is very poor (expected).  The whole thing is then is handed to gmsh in a compound surface with a compound line boundary and remeshed.  The results so far have been quite good. The two figures attached show the initial coarse mesh (viewed directly above so you can't see the surface shape) and the version after remeshing.  Pretty nice!
