+*  - store asset arena to asset structure
+*  - condense get_X_ByPath functions with assetLoad functions
+*    - move to asset interface
+*  - load diffuse texture automatically when loading a model
+*  - move entity structure and functions to new file?
+*  - load diffuse texture into OpenGL, and store GLTexture structure onto
+*    GLContext
+*	- need a cache algorithm starting in initEntity()
+*		- check for GLTexture by path hash
+*		- load texture into gl if not cached
+*		- pass result GLTexture to loadGLMesh()
+*  - update loadScene function with textured models, and test texture loading
