The indices are now checked at caller level.

This option is mainly intended for comparison with existing systems. It
should not be used for operational systems and the full Duvenhage
algorithm with line-of-sight bending in geodetic coordinates should be
used instead.

This will allow implementing inverse localization.

This better matches physics naming conventions.

This setting is not intended to be used often (in fact it should be used
only for validation against other systems), so forcing user to set it in
all cases was a bad idea. Now the default configuration is to compensate
and if user does not want to compensate, he can inhibate it by calling a
separate method after construction.

We now use directly Orekit PVCoordinates and Apache Commons Math
Rotation classes.

We use directly the Orekit GeodeticPoint now.
