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).

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.
