Detailed Description

Determines the location of a subline along a linear Geometry.

The location is reported as a pair of LinearLocations.

Note
Currently this algorithm is not guaranteed to return the correct substring in some situations where an endpoint of the test line occurs more than once in the input line. (However, the common case of a ring is always handled correctly).
