Tutorial docs

Hey devs and artists! I've opted to make a Tutorial doc instead of videos because I'm honestly just now finding out how terrible at that I am lol.

I've also fixed a widespread bug that caused elements to not display properties properly when only one of an asset or character or variable was available!

I've also come to realize that my program was NOT visible for a long long while... wow I feel stupid heh heh. Should be there now!

Hope the doc helps everyone with an problems. Please bring any issues to my attention and i will address them promptly! Happy creating!
