Editor: Region Map drag & drop
Drag: Drag selected cells. Note that the selection can contain cells that don't exist (yet). These should also be included in the drag option.
Drop: Drop region onto a single cell should change the region of that cell. Also the applied region should be stored into mRegionId.
