Luc Maisonobe c23335bae4 Fixed Luther step interpolator error.
Now all tests related to the Luther integrator and step interpolator
pass.

Luc Maisonobe b5c1893a70 Added test for Luther step interpolator.
BEWARE! This test does not work yet. It confirms there is a problem
in the step interpolator for Luther integrator.

Luc Maisonobe 548dfd8bea Added test for Luther integrator.
BEWARE! This test does not work yet. The integrator seems to be wrong
for now, probably at step interpolation level because the Butcher arrays
are consisten with the regulat integrator.

Luc Maisonobe 41bbbd468a Starting tests on field ODE!
At least we can now run some code ...

Luc Maisonobe 6d1fb4dc3e One step towards immutable step interpolators.
The interpolators do not expect anymore the y and yDot arrays to
be shared with integrator and be updated by it.

Luc Maisonobe c4dd533843 The step interpolator should refer to the integrator array.
This behavior will be changed later on to get immutable objects.
For now, we still rely on arrays being shared between the integrator and
the interpolator.

Luc Maisonobe d4b56e80b4 Removed step interpolator prototyping.
We can just use a factory method in the integrator for building an
interpolator each time we integrate.

In the long term, we will even recreate it at each step so the
interpolator can be immutable.

Luc Maisonobe 40faa3ef12 Replaced static double array constants with field constants.
This will allow for example setting up ode integrators using Dfp
instances with increased accuracy, including for the ode coefficients
themselves.
