Multiple material 3D model files

Multiple material file formats

When we have lots of auto-change extruders in Mendel (and also can swap them easily by hand in Darwin), then we'll need to represent objects made by more than one material. This page sets out and discusses the file-format definitions for that.

[If someone gets half a chance, can they check out industry standards for the multiple material file problem? I expect, like STL itself, they'll be rubbish and we can do better, but we ought to know...]
