MATH-698 Made "CMAESOptimizer" a subclass of "BaseAbstractMultivariateSimpleBoundsOptimizer". The original code does not support mixing finite and infinite bounds (no constraints) on the variables; a check for this incompatibility is thus performed, throwing a "MathUnsuppportedException" if failing.
