/*
Unfortunately aiNode has bone structures and meshes too, yet we can't assign
the mesh to a bone aiNode as a skin may refer to several aiNodes. Therefore
I've decided to import into this structure:
aiScene->mRootNode
| |->mMeshes (all the meshes)
| \->children (empty if there's no skeleton imported, no meshes)
| \->skeleton root aiNode*
| |->bone aiNode
| | \->subbone aiNode
| |->bone aiNode
| | ...
| \->bone aiNode
\->mMeshes[]
\->aiBone, referencing mesh-less aiNodes from above
* - normally one, but if a model has several skeleton roots, then all of them
are listed in aiScene->mRootNode->children, but all without meshes
