*
* This method receices the position and normal of a vertice.
* Whatever Vector3 is returned will be the new position of the vertice.
*
*
* For example, the line below randomly moves the vertice.
*
* basePosition += new Vector3 (Random.Range (-0.1f, 0.1f), Random.Range (-0.1f, 0.1f), Random.Range (-0.1f, 0.1f));
*
*
* You also have access to the ModifierObject, which handles this modifier along with any other ones attached to the same GameObject.
* From there you can info you might need.
*
* For example, Time.time doesn't work very well when calculations need to take place over multiple frames. If you want a value to animate over time, use modObject.Time!
