Basic principle

GENTLEMAN proposes a Java interface. Using this Java interface is relatively simple but as GENTLEMAN needs a lot of data as inputs the most important difficulty will be to initialize them.

So, the developer will have to:

1. Initialize a GENTLEMAN propagator.
2. Execute the propagation to store the output in a spacecraft list.
3. Initialize a GENTLEMAN object.
4. Initialize a GtmBuilder builder object.
5. Call the needed method of the builder object.
6. Get the results via getters methods.
