Test suite cleanups, convert Coord2D to Vector<T, 2>.

- The standard SimpleSuite setup now include flags to suppress printing
  the report in addition to silencing the test runs. This is useful in
  automated testing.
- Point2D and Polar2D in Coord2D have been converted from custom types
  to Vector<int, 2> and Vector<double, 2>, respectively.
