*Removed some old HE_Mesh 2014 code for a refactor that isn't going to
happen.
*WB_coordinateSequence is now a class instead of an interface.
WB_SeqPoint and WB_SeqVector are WB_Coordinate implementations that
allow a dynamic view into the compact sequence, useful for calculations
and for not having to write all code double.
*Changed WB_GeodesicI code so mesh is now generated as a convex hull.
Strictly not correct for some low v tetrahedral spheres but all the face
bookkeeping isn't worth the hassle.
