Avoid unnecessary indirect includes for the module, which would slow down compilation. Avoid "using std" which is generally not considered good practice since it's helpful to see what namespace things are from. This is just a general cleanup of the area. I was trying to understand it better to reduce redundant mesh topology storage but finding that some intermediate cleanups would be helpful to ease the change.
