Creation of the EllipsoidTest class.

Implementation of a test checking the following construction methods :
- createEllipsoidFromSemiMinorAxis
- createEllipsoidFromInverseFlattening
- createEllipsoidFromEccentricity
Implementation of a test checking the basic ellipsoid defined in org.cts.Ellipsoid.

For each ellipsoid, the test check the value return by each getter defined in the Ellipsoid class.
Implementation of the tests checking the transformations between latitude and isometric latitude.

This tests are based on IGN testing values.
Implementation of the tests checking the calcution of :
- the transverse radius of curvature at a certain latitude.
- the curvilinear abscissa correpsonding to a certain latitude.

This tests use IGN's testing values.
Implementation of the tests  checking the following methods :
- meridionalRadiusOfCurvature.
- arcFromLat.
- latFromArc.
