/**
* \brief Edge Split
*
* Splits an edge. \a v should be one of the vertices in \a e and defines
* the "from" end of the splitting operation: the new vertex will be
* \a percent of the way from \a v to the other end.
* The newly created edge is attached to \a v and is returned in \a r_e.
* The original edge \a e will be the other half of the split.
* <pre>
* Before: v
* +-----------------------------------+
* e
*
* \return The new vert
* After: v v_new (returned)
* +-----------------+-----------------+
* r_e e
* </pre>
*
* \param e The edge to split.
* \param v One of the vertices in \a e and defines the the "from" end of the splitting operation,
* the new vertex will be \a fac of the way from \a v to the other end.
* \param r_e The newly created edge.
* \return The new vertex.
