updated optimization main interfaces to handle scalar and vectorial functions

722fc97a7a
started refactoring of optimization framework:
...
- created subpackages optimization.direct, optimization.general,
optimization.linear (currently empty) and optimization.univariate
- removed packages analysis.minimization and estimation
- renamed all Cost-related interfaces/classes into Objective
(this allows both minimization and maximization)
- added a few new general interfaces
This work is not complete yet. The direct and general packages classes
are very close to the former design, they have almost not been changed
structurally.
