continued refactoring of optimization framework:
...
- improved general interfaces at top optimization level
- added a simple implementation of ConvergenceChecker (ObjectiveValueChecker)
- added a general multi-start wrapper
- changed the direct search optimizers to the new interfaces
This work is still not complete yet. The general package classes
are very close to the former design, they have almost not been changed
structurally.

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.

Failed attempt to implement Strassen matrix multiplication on recursive layout as
...
described in Siddhartha Chatterjee, Alvin R. Lebeck, Praveen K. Patnala and Mithuna
Thottehodi paper "Recursive Array Layout and Fast Matrix Multiplication".
As of 2009-02-13, this implementation does not work! The padding at left and bottom
sides of the matrix should be cleared after some operations like scalerAdd and is not.
Also there is a limitation in the multiplication that can only process matrices with
sizes similar enough to have the same power of two number of tiles in all three
matrices A, B and C such that C = A*B. These parts have not been fixed since the
performance gain with respect to DenseRealMatrix are not very important, and the
numerical stability is poor.
This may well be due to a bad implementation.
This code has been put in the experimental directory for the record, putting it into
production would require solving all these issues.
