Realistic Swimming Animations

This is a set of 18 hand-crafted (not motion capture!) third person swimming animations, comprised of 6 core motions and several directional variants to allow smooth, dynamic turning.

- Uses the Mecanim Humanoid system so the animations can easily be used on other characters
- Includes underwater and surface animations, with each having one idle and two types of swimming strokes
- A sample Mecanim state machine is included to demonstrate blend trees and allow animations to be triggered via UI in the demo scene
- All animations are in-place only
