MAM Single Shape Layer No Pins No Crystals

This simple MAM was designed to minimise the time to switch between layers. As it is it will switch to a new layer shape in about 2 minutes (time from switching input shape definition, to first correct shape being output). It's not very efficient in terms of amount of inputs (4 full space belts of shapes, 7 full space belts of colors) to final output (3 single lanes, 1 on each layer), but it's very quick to change over. As noted in the name it can only handle a single layer of a shape, no pins, no crystals. Will be happy to see people improve on this.
