DiagramGrid: Build meaningful triangles from the skeleton of the diagram.

DiagramGrid now sees which triangles are there in the skeleton, but also
discards the triangles which have less than 2 edges corresponding to
morphisms.  Such triangles may appear because of the how the skeleton is
constructed (cf. previous commit) and are irrelevant to laying the
diagram out, because only one edge of them will eventually be shown.
Note that such triangles are actually redundant in the sense that the
objects and morphisms they refer to will eventually be pulled into the
grid by other, more meaningful triangles.  This redundancy arises from
how the triangles are built and may be a point of further improvement
and/or optimisation.
