Implement a "french gabarit" i.e. a manhattan of constraints along the planned path. Constraints are speed constraints, level constraints to achieve a speed, a level, etc. before, after, on, a geo point.

Manage a set of Abaquus for the continuous descending phase. Need a strategy here to decide to descent slowly from a big distance to the convergence point, or descent quickly. Strategies are based upon : fuel consumption, time in the air opposed to crew salaries, delay in the arrival that will constraint the company to pay for passenger missing their correspondence...

Please provide a pull request for any improvement. As soon as a Unit test is there with Asserts, this is OK.
