Changes made to code:
- Resolved the nullPointerException for the getGrid() issue.
- Created a thisGrid() method in BWorld that returns the current Grid.
- Set a Grid object grid to this, and used grid instead of getGrid();
- @elysia simplified your code into one shorter method.
- attempted to write the code to paste the processed row/column back onto the Grid.

Issues
- Null Pointer Exception came back after coding some more.
- specifically, this issue happens at paste().
