New Take and Skip methods for worksheet ranges

A new set of methods that makes it easier to access specific rows/columns in a range. These methods are, for example, useful when working with charts, tables and the output of dynamic array formulas.

            
// newRange will be B3:C8
var newRange = worksheet.Cells["A1:G8"]
                  .SkipRows(2)
                  .SkipColumns(1)
                  .TakeColumns(2);
