d088734d25 Serialization changes for optimization. 
Still need to add junit test, but for this it doesn't look like a blocker.

aaf87073b5 changed again the Adams-Bashforth and Adams-Moulton integrators 
they now both use Nordsieck representation
this is the first really usable implementation, it still integrates only with fixed stepsize,
but thanks to Nordsieck representation they will be improved to adaptive stepsize soon

7de1b628c6 added a lazy evaluation for step interpolators 
moved the possible exceptions from setInterpolatedTime (which now does almost nothing) to getInterpolatedState and getInterpolatedDerivatives (which now do the evaluations)
renamed an internal function to make sure people overriding it don't forget to set the derivatives

ca9d46257a merged the decomposition package back to the linear package. 
This will allow later improvements as decomposition algorithms
will be able to see implementation details when more efficient
matrices implementations (for example based on blas) are added

83dd172df8 More serialization changes. 
Not clear what I should do with RandomAdaptor.  So I've let it remained broken (no public no-opt construtor, but Serializable).

Feel free to -1 anything that I've stripped Serializable from and you care about, but I think I've been pretty conservative.

e33f09ce4f completely redesigned Adams-Bashforth and Adams-Moulton integrators 
they are now provided by a single class and use the Nordsieck form
with higher derivatives at current step instead of classical form
with only first derivatives but at several steps.
The implementation is simpler for both the integrators and the step
interpolator and it allows a future enhancement with adaptive stepsize.
