Adds a new definition partitioning V(T'_{f'}) \ V(f') by geometric
location relative to the face f':
V_out(T'_{f'}) := { v in V(T'_{f'}) \ V(f') : v lies outside the
closure of f' }
= "outer spokes"
V_in(T'_{f'}) := { v in V(T'_{f'}) \ V(f') : v lies inside the
open region f' }
= "inner spokes"
These are well-defined because the boundary walk of f' is V(f') by
definition, so no element of V(T'_{f'}) \ V(f') sits on ∂f'.
In the spoke-only setting (T'_ann = C_{n+m}), the inner spokes of
the inner face are the O-side non-annular dual vertices and the
outer spokes are the source-side non-annular dual vertices (and
vice-versa for the outer face).
Paper stays at 10 pages.
