A representation made up of a single polyline or "polygonal chain", which may be closed or not.
Definition from Wikipedia (http://en.wikipedia.org/wiki/Piecewise_linear_curve):
A polygonal chain, polygonal curve, polygonal path, or piecewise linear curve, is a connected series of line segments. More formally, a polygonal chain P is a curve specified by a sequence of points \scriptstyle(A_1, A_2, \dots, A_n) called its vertices so that the curve consists of the line segments connecting the consecutive vertices.
In computer graphics a polygonal chain is called a polyline and is often used to approximate curved paths.
BUSINESS RULE: To record a polyline the writer software must give the values of the geometry of each node in an order corresponding to the logical series of segments (edges). The geometry of a polyline must be a 1D array of points.
A simple polygonal chain is one in which only consecutive (or the first and the last) segments intersect and only at their endpoints.
A closed polygonal chain (isClosed=True) is one in which the first vertex coincides with the last one, or the first and the last vertices are connected by a line segment.
