Given a set of vertices and edges (varr, earr), find out if all those vertices are filled in by existing faces that only use those vertices.
This is for use in cases where creating a face is possible but would result in many overlapping faces.
An example of how this is used: when 2 tri's are selected that share an edge, pressing F-key would make a new overlapping quad (without a check like this)
earr and varr can be in any order, however they must form a closed loop.

A vertex is non-manifold if it meets the following conditions: 1: Loose - (has no edges/faces incident upon it). 2: Joins two distinct regions - (two pyramids joined at the tip). 3: Is part of an edge with more than 2 faces. 4: Is part of a wire edge.

The function takes a vertex at the center of a fan and returns the opposite edge in the fan. All edges in the fan must be manifold, otherwise return NULL.

Given 2 verts, find a face they share that has the lowest angle across these verts and give back both loops.
This can be better than BM_vert_pair_share_face_by_len because concave splits are ranked lowest.
