Added method to compute a^x for double a and DerivativeStructure x.
...
This takes care of special cases like a=0, but encounters the same
limitation as rootN near the singularity 0^0. Combined derivatives like
order 2 or higher with respect to canonical variables give NaN and not
+/-infinity. First derivative with respect to a single variable works
well and provided the correct infinity.

Simplification of the code introduced in revision 1508481. The changes
only focus on the "fluent API" aspect (rather than also try to achieve
thread-safety through immutability).

optimizers (i.e. replace the current "BaseOptimizer").
