TODO: Returns the value of the derivative of the function func1 by another function func2 at the point domainValue.

Todo:

Please, implement me!
This method objective requires clarification: are we calculating either (func1*func2)' or func1'*func2'?

double QUESO::FuncTimesFunc1D1DFunction::value ( double  domainValue ) const

virtual

Returns the value of the multiplication of a function func1 by another function func2 at the point domainValue, i.e. returnValue = func1(domainValue)*func2(domainValue) .

This function calls the value() method of the both functions and multiplies their return value with one another.
