Copy Rows/Columns

[OssianEPPlus]

Create a ExcelRangeRow.Copy and ExcelRangeColumn.Copy method. So users don't have to rely on ExcelRangeBase.Copy e.g.
C# sheet.Cells["4:5"].Copy(sheet.Cells["7:8"]);
Also consider if functionality should be added to ExcelRangeBase.Copy so it also copies row height and/or column height.
