Major Description
When the Append/Increment contains a CellVisibility, we will rewrite this new tags in to the new Cell. There while copying the non vis tags, we exclude TagType.VISIBILITY_TAG_TYPE only. So the old cell can contain TagType VISIBILITY_EXP_SERIALIZATION_TAG_TYPE and we will copy that one, and next while creating Tags for the new CellVisibility we will add this tag again. So a cell after 100 Increments will contain 100 tags of type VISIBILITY_EXP_SERIALIZATION_TAG_TYPE!
