The intro page does not explain how MJ start running when there's no rule matched at the first place #47

Take the simple Growth model for example, when you start the MJ it's all Bs on the grid so there's no "WB" to start with, so in what mechanism does MJ put a W in center (or via any other way) so that a "WB" can be matched therefore Growth can actually "grow"?

I guess the property "origin=True" might be the trick, but after a rough browsing I somehow can't find the right source (and it seems to me that it could be more "configurable" than just a boolean) to this design and I think this needs some serious explanation at the first section of the intro.

It's indeed the origin, I explain this in syntax overview:

If origin is set True, the interpreter creates a pixel at the center of the grid with the value equal to the second value in values. For example, values="YRBAN" origin="True" creates a yellow screen with a red dot in the center.

Oh I missed it, thanks.
