* @brief Single parameter function abstract base class
*
* This class implements the abstract interface for a one parameter function.
* This function is for example used for integration or numerical computation
* of derivatives. This class has no members. The only pure virtual method
* that needs to be implemented by the derived class is the eval() method
* that provides function evaluation at a given value x, e.g. y=eval(x).
