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.
JIRA: MATH-1131

0714c7cbe6 MATH-1128 
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.
