Title: Use Great Circle Formula in the length() method.

* Remove computation of the length() from Collection and moved it in LineString Class, just like greatCircleLength().
* Optimizing method length() and greatCircleLength(), cleaning useless vars.
* Removed length() method from MultiLineString, which is now useless.
