EvaluatedFunction not used

[Stephen Siegel]

There is an interface EvaluatedFunctionIF and class EvaluatedFunction which are not used. The DynamicFactory's evaluatedFunction method does not return an instance of this type, it returns an instance of SymbolicValue.

The method should probably return an EvaluatedFunctionIF, because this provides a means for the user to get the function and point from the value. Solution can mimic similar situation for ArrayValue or RecordValue.

[Stephen Siegel]

Fixed by getting rid of EvaluatedFunction. Leaning towards simplicity and fewer classes in value package.
