In the example A, faces f1 and f2 are joined by a single edge, and the euler can safely be used. In example B however, f1 and f2 are joined by multiple edges and will produce an error. The caller in this case should call bmesh_kernel_join_edge_kill_vert on the extra edges before attempting to fuse f1 and f2.

This function assumes l_sep is a part of a larger fan which has already been isolated by calling bmesh_kernel_edge_separate to segregate it radially.

Separate Vert.
BMesh Kernel: For modifying structure.
Names are on the verbose side but these are only for low-level access.
Separates all disjoint fans that meet at a vertex, making a unique vertex for each region. returns an array of all resulting vertices.
