* Added my own model and license to Raylib exclusively created by me and provided for use in the examples (and other projects if anyone decides to) * Use animation vertices on initial load if possible. * Added girl model to model example * Revamped GLTF model loading as it was wrong by default. Also updated some comments. GLTF models were loaded only by mesh but they should be loaded recursively by hierarchical nodes because tehre are some static node transformations that are to be applied to the vertices. It also resulted in more meshes being included in some models. It is the correct way of loading GLTF and what is suggested in the official examples. Currenlty limiting to only one scene but more can be included later. * Refactored the new names and structure of extracted functions. * Safer and easier read value. * Made reading easier for accessor->bufferView->buffer in GLTF. Now there is no need to check for supported types or anything. * Correct inclusion of limits.h in the cases of MSVC based compilers vs the world * Removed weird example file

* To export a model from blender, make sure it is not posed, the vertices need to be in the
|
|
* same position as they would be in edit mode.
|
|
* and that the scale of your models is set to 0. Scaling can be done from the export menu.
