Create a basic simulation Unity project.

[matt-ashman]

This work is to create a simple Unity scene with class library enabling basic simulation functionality including:

• Simple enviroment with some sort of sky box:

  • https://docs.unity3d.com/560/Documentation/Manual/HOWTO-UseSkybox.html

• Camera sensor simulation (initially standard pinhole virtual camera)
• Trajectory generation (initially just constant velocity and random)
• Video recording functionality
