Preliminary implementation of ASCII PLY file parsing
Preliminary implementation of ASCII PLY file parsing

This is not yet generic enough. While I can parse any combination of
data type and vertex type, the resulting simplicial complex will not
contain any weights.

For this to work, I should attempt to parse some _properties_ stored
along with the mesh.
