Hello!

I have written a tool based off of Assimp that converts collada/fbx models to a custom format.  For some reason assimp is omitting some of the mesh's bones from the aiMesh::mBones list, but they still appear in the aiScene::mRootNode node tree.  This causes my converter to mangle the bone tree structure, because some of the bone's parent bones don't appear in the aiMesh::mBones list!

Here is an example.  The "RiggedModel_Final_FootNull" gets omitted from the aiMesh::mBones list but its children are not.  Why does assimp do this and how would I fix it?  It would be great if assimp would store all bones in the bone list.

<node name="RiggedModel_Final_FootNull" id="RiggedModel_Final_FootNull" sid="RiggedModel_Final_FootNull" type="JOINT">

I really appreciate any and all help!
