mesh validation function to report errors and help debug bad data generated by modifiers.

detects...
- invalid vertex range for edges/faces
- duplicate indices in edge/face
- duplicate edges/faces in mesh
- missing edges data in faces

At the moment it doesn't correct errors, but eventually it will do this.
