BUG: capture infinite loops creating LinearRings

Using current implementation, a multilinestring is used to construct
linestrings which include boundary points in order to make suitable
LinearRings, however, this can result in infinite loops as points are
determined by distance measures.

This fix maintains a list of linestring indices, ensuring that no
linestring can be re-added.

BUG: non ccw polygon being interpreted

A workaround within cartopy is provided which changes the orientation
of a polygon if its exterior is of non counter-clockwise order.  The
order is important in cartopy while it isn't in matplotlib.  This is a
workaround for a bug present in mpl, as it is supposed to provide only
ccw polygons.
