Represents an embedding of a planar graph.
A planar embedding is represented by a
list of faces. Each face is represented by a list of
darts which describe the border of the face.

The resulting embedding does not consider the current drawing of the graph.
Querying the planar embedding after changes to the underlying graph structure may produce exceptions.
Creates a new embedding for the specified planar graph.

Gets a IList<T> of face lists.
More precisely, each entry of this list is another list that contains all
darts of a face.
Gets the IList<T> that represents the outer face.
The returned list is also contained in the
face lists.
Returns the cyclic next dart of the given dart.
