-        Refactoring of some classes in package "optimization.general" to remove
-        code duplication and to allow the implementation of optimization algorithms
-        that do not use derivatives.
-        Created interface "BaseMultivariateRealOptimizer".
-        Created classes "BaseAbstractScalarOptimizer" and "AbstractScalarOptimizer".
-        "MultivariateRealOptimizer" and "DifferentiableMultivariateRealOptimizer"
-        both extend "BaseMultivariateRealOptimizer".
-        "AbstractScalarOptimizer" extends "BaseAbstractScalarOptimizer" and
