Refactored anim graph data usage and evaluation.
- Refactored NodeSocketAccessor to NodeDescriptor. - Connections are wired up during AnimGraph instantiation. - Output and input sockets point to the same memory location. - No re-wiring needed during evaluation. - AnimGraph are pre-allocated (refactoring for less memory usage postponed). - Evaluation of AnimGraph now possible from the editor.AnimGraphEditor
