Class Paths
This structure is fundamental to the Clipper Library.
It's a list or array of one or more Path structures. (The Path structure contains an ordered list of vertices that make a single contour.)
Paths may be open (a series of line segments), or they may be closed (polygons). Whether or not a path is open depends on context. Closed paths may be 'outer' contours or 'hole' contours. Which they are depends on orientation.
