71fd124ddb Constrained EmpiricalDistribution sample/getNextValue methods to return 
values within the range of the data; correctly linked RandomGenerator to
superclass so that RealDistribution reseedRandomGenerator method works.

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.

random order. This seemed to be the case up to Java 7 but
not always in Java 8.
