Detailed Description

Another concrete instantiation of the hole, this one should be sufficiently general for most non-polygonal purposes.

The user supplies, at the time of construction, a reference to a vector of Points which defines the hole (in order of connectivity) and an arbitrary Point which lies inside the hole.
