JamWils / UnityPhysicsRayCastTest.cs

This is some sample code on how to test Unity Physics properly, this uses version 1.0.14. This sets up a sphere collider and draw a ray through the center of it along the y-axis. Please note the `LocalTransform` component, this needs to be included for the collider to work properly in a unit test.

type Person struct {
