Bugfix: Degenerate Polygons and the Shapely Formatter

The contours.core.shapely_formatter could not handle single point
polygons or polygons with single point holes.

• In the case of regular contours theshapely_formatter now returns
  shapely.geometry.Point objects for single point contour lines.
• In the case of filled contours the shapely_formatter now removes
  single point polygons and single point holes in polygons as they are not well
  defined for filled contours.

Grid Contours

The contours.quad.QuadContourGenerator class provides an interface
into Matplotlib's contour generation algorithms for curvilinear, rectilinear,
and uniform grids.

Output Formats

Contours can be returned in 1 of 3 formats:

• List of NumPy arrays.
• Single NumPy array (MATLAB style).
• Shapely geometry elements.
