Naming for geometric objects

[bacusters]

In our kernels, we name everything prefixed with Movetk e.g. MovetkPoint, MovetkLine. This prefix, however, does not really add any value. Would it make sense to simply rename them to Point, Line etc.? This makes using movetk with user defined kernels perhaps easier, since they do not need to use the prefix.

In addition, it may be convenient to add aliases for the geometric objects in the movetk::geom namespace, e.g.

template<typename Kernel>
using Point = typename Kernel::Point; //or MovetkPoint, if we decide not to remove the prefix

This makes using these types easier, then you can do movetk::geom::Point<Kernel> instead of typename Kernel::Point. This is similar to how CGAL approaches geometric objects.
