Fix for Polygon.normalize() to work on CoordinateSequence (#254) (#262)

* Fix for Polygon.normalize() to work on CoordinateSequence (#254)
* Necessary additions to CoordinateSequences utility class (#188)
  - minCoordinate, minCoordinateIndex
  - indexOf
  - scroll
* Create overload of Orientation.isCCW with CoordinateSequence as ring
  argument partly (#188)
* Wire Orientation.isCCW(CoordinateSequence) with some EdgeRing classes
