      Description

      A DerivativeStructure and UnivariateDifferentiableFunction are great tools if one needs to investigate the whole function but are not convenient if one just needs derivative in a given point.
      Perhaps you could add some helper methods to FiniteDifferencesDifferentiator or to utility class like FunctionUtils. Also it would be good to have helper methods to get the derivatives of UnivariateDifferentiableFunction or MultivariateDifferentiableFunction as simple Univariate or Multivariate functions (or vector-functions).
