a4ef3f9941 fixed a warning about a mission serializeVersionUID. 
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.

d8575cde51 changed the Adams-Bashforth and Adams-Moulton multistep integrators to adaptive stepsize. 
this was made possible thanks to the Nordsieck representation of integration state

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.

913ff1facc More Serialization changes, mostly for ode and friends. 
Unfortunately, had to leave some abstract base classes as Serializable, since they had no senible default construters.  But left them with meaningless UIDs, to break anyone that doesn't override it.

Of course, if anyone has a better patch, I'm happy to implement it.  At this point, the serialization changes for [math] should be almost done.
