Now, only cells that have been used are cleared. This is achieved by using a "occupied" memo on the Row itself. The value, `occ`, is updated wherever the Row is accessed mutably, and it's cleared to zero in Row::reset. The tests for grid scroll_up and scroll_down were updated to include a test on the value `occ` and slightly refactored, but are otherwise equivalent to the previous implementation of those tests. Because of the change to the `Row` struct, the ref tests were updated so Deserialization keeps working as expected.
