Detailed Description

S H E L L

When a shell encloses volume, it's done entirely by the list of faceuses.

The wire loopuses (each of which heads a list of edges) define a set of connected line segments which form a closed path, but do not enclose either volume or surface area.

The wire edgeuses are disconnected line segments. There is a special interpetation to the eu_hd list of wire edgeuses. Unlike edgeuses seen in loops, the eu_hd list contains eu1, eu1mate, eu2, eu2mate, ..., where each edgeuse and it's mate comprise a *non-connected* "wire" edge which starts at eu1->vu_p->v_p and ends at eu1mate->vu_p->v_p. There is no relationship between the pairs of edgeuses at all, other than that they all live on the same linked list.
