• Adjust the model definitions to accept input of multiple model (.mu) files, as well as allow for disabling specific transforms in those models at the lowest levels.
• Allow for each 'sub-model' to be positioned, rotated, and scaled independently.
• During model construction, setup all transforms from all models as-per their definiton (loc, rot, scale)
• Present a single 'root' transform to external interfaces (all sub-models parented and positioned properly relative to the root transform).
• Texture sets already work on a 'per transform' basis, so not much should need to be altered for that functionality
• Will need to investigate what changes would be needed to the newly added animation handling routines.

These changes will open up handling options for many currently un-usable models from other mods that rely on internal mesh-switching setups (b9-part switch, old firespitter switch); models that contain many sub-models.

Will also allow for each 'model definition' to use entire (or partial) models from any .mu file. So if you wanted an 'extra long' tank body, you could pre-weld several (even the same) tank segments in the lowest level of the model definition.
