Many source file name and data type are prefixed by "skeleton" before, now all are refactored.
The class MeshResultContext represents the outcome of mesh generation before, now we have material, pose and animation, so we just rename it as Outcome.
Curve editor has been removed from this commit.
Instead of let user edit customized curve for motion, we provider presets. It's much more easy to add motion than before.
