Tutorial 1

Description

Builds on the previous tutorial to add an agent and some moveable obstacles.
Implements basic collision against the environment and against the moveable obstacles.

When you run the application you should see a mesh rendered in the testbed and be able to move the camera with the testbed controls, as in 'BasicApplication'.
You can also place or move an agent with '4' and two obstacles with '5' and '6'.
You should not be able to get the agent into a position in which it collides with either of the obstacles, or overlaps the edge of the mesh.
