The ParameterDriver class has been introduced in Orekit for
the orbit determination feature.

Replaced raw arrays with Stream instances to avoid giving access
to internal arrays.

Version after 0.7.4, but not 0.7.6, hence 0.7.5.

The previous jacoco plugin version was not compatible with Jenkins
anymore.

This allows for example to retrieve the DEM elevation for a
latitude/longitude pair.

This can be used to set up min/max search lines.

This is still preliminary work, convergence seems slightly wrong.

Some attitude laws constructors used in tests have been deprecated.
