- accuracy of current implementation of Beta.logBeta
- standard deviation of error (in ulps) is now provided for all special
functions that have already been evaluated.

Renamed "computeJacobian" to "computeWeightedJacobian" to relect what is
actually done.
Made "setCost" a "protected" method (as it should only be modified according
to the optimum found by the subclass's algorithm (defined in "doOptimize()").

Made "GaussNewtonOptimizer" use the new methods in base class
"AbstractLeastSquaresOptimizer" instead of modifying the (now
deprecated) protected fields.

Deprecated "protected" fields.
Created new methods (that take arguments and return a value) to
replace those that operate on protected fields.
Removed call to deprecated methods in unit tests.
Added public method "setCost" to replace the direct assignment to
a protected field.

First steps to enhance encapsulation (goal is to remove the "protected"
fields): used new API (MATH-874).
Replaced explicit loops with matrix operations.
Disabled a unit test that does not pass anymore.

First steps to upgrade the API of the classes in "o.a.c.m.optimization.general".
Please note the introduction of a "Weight" matrix (whereas the current code
assumes that the weights are given as an array).

Reduced number of overridden public "optimize" methods (replaced by protected
"optimizeInternal"): whenever the code is ready for 4.0, only the base class's
"optimize" method should define the public API (subclass specifics are handled
in overridden "optimizeInternal" which must call the base class's version to
handle the common setup).

Using different seeds for the component distributions to avoid getting
the same sequence of random numbers for all of them. Update to the
"testSampling" unit test contributed by Jared Becksfort.

The older API is still supported as of version 3.1, but is implemented
by wrapping the user function into the new API and then calling the new
code.

The converters allow to convert back and forth between the older
and the newer differentiation API. They are considered temporary methods
for version 3.1 and will be removed in 4.0 as only the new API will
remain.

This version should be much more robust on polygons computation than the
earlier ones. Note that the hyperplaneThickness parameter is a key
tuning parameter in difficult cases like the one involved in the issue.
As shown in the corresponding unit test, the value had to be raised to
1.0e-8 in order for the test to pass correctly.
