FillForwardExtensionFillForwardT(IEnumerableT, FuncT, Boolean) Method
            Returns a sequence with each missing element in the source replaced
            with the previous non-missing element seen in that sequence. An
            additional parameter specifies a function used to determine if an
            element is considered missing or not.

- source  IEnumerableT
- The source sequence.
- predicate  FuncT, Boolean
- The function used to determine if
            an element in the sequence is considered missing.
- T
- Type of the elements in the source sequence.
IEnumerableT
            An 
IEnumerableT with missing values replaced.
            In Visual Basic and C#, you can call this method as an instance method on any object of type 
IEnumerableT. When you use instance method syntax to call this method, omit the first parameter. For more information, see 
Extension Methods (Visual Basic) or 
Extension Methods (C# Programming Guide).
 
            This method uses deferred execution semantics and streams its
            results. If elements are missing at the start of the sequence then
            they remain missing.
