Improved Dormand-Prince 8(5,3) step interpolator accuracy at step start.
...
The previous step is preserved and if interpolation time is in the first
half ot the step, then interpolation is based on step start, otherwise
is it based on step end. Previously, interpolation was always performed
with respect to step end.
If this trick proves useful, it will be extended to other Runge-Kutta
type step interpolators.

Fixed a bad interaction between step handlers and event handlers in ODE
...
integrators.
The problem was due to an internal array from the step interpolator that
was changed by the step handlers. These array was expected to contain
the state at event time, but was overridden later on. the solution is
simply to clone the array. Note that the fact the array is reused *is*
documented in the javadoc and is a feature of the interpolators ...

Added adapters for simple bounds constraints optimization.
...
The adapters are useful only for optimizers that do not support simple
bounds constraints by themselves (i.e. Nelder-Mead and Torczon's
multidirectional). Two adapters are available, one performs a mapping
between the whole real range and the bounded range (bounds being set
component wise), and one uses a penalty function.
