The concept `GetPlacement` describes the requirements for the <I>policy
function object</I> which gets the <I>collapse placement</I> of an edge,
that is, the new position of the vertex that remains after a
halfedge-collapse operation.
The placement returned is a `boost::optional` value (i.e., it can
be absent). An absent result indicates that the edge should not be collapsed.
This could be the result of a computational limitation (such as an overflow),
or can be intentionally returned to prevent the edge from being collapsed.
