Filtering is based on an user-provided enabling predicate function. This
allow for example to dynamically turn some events on and off during
propagation or to set up some elaborate logic like triggering on
elevation first time derivative (i.e. one elevation maximum) but only
when elevation itself is above some threshold.

Fixes issue #215.

Github: closes #5

Previously a generated ephemeris may not have been available at the start and
stop times used for propagation because of numerical precision issues. Now the
real start and end AbsoluteDates are used if they are equivalent to the double
representation of time. The public interfaces ModeHandler and StateMapper were
changed. Includes test cases for the numerical and DSST propagators.

Fixes #210

Works for anomaly, latitude argument, or longitude argument, either
true, mean or eccentric.

Fixes issue #213.

member. Minor changes to other classes to allow numerical propagation of
the modified class.

equinoctial and keplerian orbit (not cartesian)

- New force model for inertial (virtual) forces
- New orbit class (derived from CartesianOrbit) that allows to define an
orbit without a central body
- Some error throws deactivated in "Orbit.java" to allow integration in
non-inertial reference frames
