built first mobile course

Built a new course! I drafted the content for the Stellarium mobile app training. 

I was surprised with the result. I thought I'd be able to cover everything in Stellarium Mobile Plus in a 2 hour course. Nope. Will need two courses! Tells you how rich the product for slates is. So that's more work... Anyway the level 1 introduction is fleshed out. Very exciting.
