Detailed Description

This class defines a polyline and is used as part of a SymbolCollection.

A polyline has a sequence of points (x, y coordinate pairs)

Basic styling such as stroke and fill are defined in the superclass Symbol.

Note that since a Polyline is typically an open shape one usually want a fill that is transparent.
