b5395fd802 be more precise on return type, we really return a Array2DRowRealMatrix,
so tell it in case some callers can use this information for optimization
(which is the case for Nordsieck transformers, they will be able to use
customized loops on matrix data for the sake of numerical accuracy)

However, should this really be serializable at all ?

4474f96263 removed lots of serialization in ODE
the only classes/interfaces for which serialization is really important in this package are the step interpolators. The reason for that is that the ContinuousOutputModel is explicitly serializable and contains step interpolators. This allows users to perform integration of any complex model and to save the result of the integration for all integration range by serializing a ContinuousOutputModel instance. This feature is a major one.

83ec0f9328 completely changed integration start phase: now the starter integrator for
multistep methods do not advance time anymore, it is interrupted at first step
end and the interpolator is used to reconstruct Nordsieck vector information at
integration start. Then the normal multistep integrators does start also exactly
at integration start and is responsible for all time advancing stuff, including
step handlers and events handlers management.
