Excel Helper Utilities Library Part Three

Obviously I've missed my self made time schedule of Monday, Wednesday, and Friday for these entries, so bare with me while I get em' published as fast as possible. With that written . . . Welcome to part three of the Excel Helper Utilities Library series. In this entry I will cover the extension of the ExcelHelper class created in Part Two. The first method is one I wrote ages ago for VB.NET, but I've added here for the C# helper. As always, tests first.
