-------------------------------------

-> Ok, the EventState class is ok now and I've checked the others.

> We would like to select g function slope in CommonsMath event detection feature.
> This would improve event detection for the final user (the possibility to ignore some events, and less computation time) and also correct a bug found while using OREKIT (see https://www.orekit.org/forge/issues/104) in our applications. 
> The modification consists in adding a method (getSlopeSelection() : int) in EventHandler, and modifying one conditionnal in the method evaluateStep (class EventState). 
> We can provide modified code and unitary tests for this feature.
