2a59e0ef4b Recovered debugging method that were removed in the previous commit.
The methods are useful and the warning about them being unused could be
solved with an annotation.

e9464c0a6d MATH-1151
New interface "ValueAndJacobianFunction" (to allow separate evaluation
of either quantity) is a precondition for lazy evaluation (and is enforced
by raising an exception early rather than wait for a failed cast).

Unit tests showing that the current implementation fails on some
special values (infinities). Other descriptive statistics values
are probably similarly affected.

f25a61670e Modified KolmogorovSmirnovTest cdf computation to use the Pelz-Good
approximation (per Simard-L'Ecuyer) for n > 140.  Removed R reference tests, as
our implementation is now different (but should be more accurate)
for the n values covered by the tests.
Also added a PI_SQUARED constant to MathUtils.

Introducing a "LazyUnweightedEvaluation": the computation of the model
and Jacobian are deferred until one or the other is actually accessed.
Class "LocalMultivariateJacobianFunction" replaces the anonymous class
that was created when calling the "model" method.
The "evaluate" method of "LocalLeastSquaresProblem" instantiates either
"UnweightedEvaluation" or "LazyUnweightedEvaluation", as requested by
the user of the "create" factory method.
