Detailed Description

Represents a list of contiguous line segments, and supports noding the segments. The line segments are represented by an array of Coordinates. Intended to optimize the noding of contiguous segments by reducing the number of allocated objects. SegmentStrings can carry a context object, which is useful for preserving topological or parentage information. All noded substrings are initialized with the same context object.
