* Removed STL headers from filameshio/MeshReader.h modified the samples to work the same, and made an effort to remedy the jsbindings although I'm not experienced with them.
* Fixed assignment operators for MaterialRegistry
* Fixed formating for MeshReader Material Registry

This class will not extend well to glTF so this cordons it off into the
filamesh namespace, which is an already-existing namespace that we use
for the things related to the filamesh file format.
For glTF we might create a new library with its own MeshReader so
this will mitigate confusion.
