Implementation of Kohonen's Self-Organizing Feature Map (SOFM).
New package "o.a.c.m.ml.neuralnet" contains base functionality for implementing
different map types, i.e. methods that project a high-dimensional space onto one
with a low dimension (typically 1D or 2D).
The SOFM-specific code is in "o.a.c.m.ml.neuralnet.sofm".

A complete generic implementation of Binary Space Partitioning Trees (BSP trees)
...
has been added. A few specializations of this implementation are also provided
for 1D, 2D and 3D Euclidean geometry. This allows support for arbitrary
intervals sets (1D), polygons sets (2D) and polyhedrons sets (3D) with all
sets operations (union, intersection, symmetric difference, difference, complement),
with predicates (point inside/outside/on boundary, emptiness, other region contained),
with geometrical computation (barycenter, size, boundary size) and with conversions
from and to boundary representation.

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.
