Modified Scene View Hiearchy by adding containers

Had to add some random files that seem to change no matter what? Hopefully they can be discarded when merging. Offenders are Rocks.meta and physics2DSettings.asset
Made the wolf's attack range smaller and removed RigidBody component
Updated AStarPathfindingProject to newest stable `release
Added global AStar object to scene, basic setup
Updated wolf to use Character Controller as Collider

Had to updated HealthBar script to accomodate (diff is 2 lines)
Wolf now only follows within a distance
Walls can no be destroyed on attack, and the gridGraph updates accordingly

Walls are obstacles and when created modify the gridGraph to make their area unwalkable
When wall are destroyed, the graphi is similarly updated to make those areas walkable again.
