Renders a sprite sheet from 3DS Max and kicks it to Unity
--Sprite Sheet Renderer by Corey Wolff
--Currently this is setup to use automatically spit out a sprite sheet to a specific location based on the
--CreateProject and CreateAsset script I made. It also wants to then have Unity chop up the sprite sheet.
--If people are intersted I could modify this to be a more generic version.
