Implement Multimatrix Function

[solidboredom]

Hello, i would like to try implicitcad to render the CSG produced by openscad, with my complex models, using full set of openscads functionality including modules() openscad gets unbearably slow, where its CSG production is still kind of bearable.
my code produces a lor of multmatrixes in the csg file. is there a way to make implicitCad understand Multmatrix() like openscad does to be able to directly interpretcomplex CSG's? or even compex openscad scripts?

Possible? yes. likely? maybe. looks simple enough.

Fixed in head but note that more related to this popped-up - matrix multiplication is not supported #414 and also radians vs degrees issue #415
