Time setting and getting methods for Julian Days, Modified Julian Days, native seconds and native days are now available that allow specifying the time system. Currently, TT, TAI and UTC are supported.

Methods have also been added that return the Greenwich mean and apparent siderial times, and the local mean and apparent siderial times that depend on the geographic longitude.

Finally, a now() method has been added that sets the time to the current time.

…ients argument (#1847)

The eval_gradients() methods duplicate much of the code of the eval() methods. To increase the maintainability of the code, the eval_gradients() methods have been removed, and the computation of partial derivatives is now done by the eval() methods if the optional gradients argument is set to true.

If an application is constructed from the command line arguments with the --help option the application parameters are not loaded, and the destructor saved before the empty parameter container to disk, which effectively emptied the parameter file. Now the desctructor only save the parameters if they have been loaded before.

The result of the log-likelihood computation was lost in a copy of the GObservations class. Now it is conserved.

…d corresponding  unit tests

The application name and version were cleared in a call of the GApplication::clear() method, but these properties should be conserved. Now they are, and a call of the GApplication::clear()  will perform the same actions than a call of the name and version constructor.

The optional linefeed parameter allows to terminate the string with (default) or without a linefeed.

Python does not understand GChatter, the type is casted to int.

The GApplication::log_parameters() method now takes a mandatory GChatter argument to enable displaying of parameters only above a given chattiness level. This avoids a log-level check in the client code. For the same purpose, the GApplication methods log_string(), log_value(), log_header1(), log_header2(), and log_header3() have been introduced (#1828).

Python wrappers have been always removed when typing "make clean", even if the wrappers have been shipped with the code. This has been corrected and Python wrappers are now only remove if they actually have been built (and hence if they have not been shipped with the code).
