    35  * GEOS computes 25 edges 3 of which composed by 3 vertices and 22 of 2 vertices.
    36  * JTS computes 25 edges 3 of which composed by 3 vertices, 3 by 1 vertex and 19 by 2.

     37  * GEOS computes 25 edges 3 of which composed by 3 vertices and 22 of 2 vertices.
     38  *  JTS computes 25 edges 3 of which composed by 3 vertices, 3 by 1 vertex and 19 by 2.
     39  * The LineString generated using all the points, according to Equals, is the same.
     40    The difference is in [source:trunk/src/noding/SegmentNodeList.cpp#L259 SegmentNodeList.createSplitEdge] refusing (in GEOS) to produce 1-vertex SegmentString.
