Have the data grid scroll on a move operation.

[ghost]

Describe the new feature being added

When an attempt is made to move a row or column outside of the viewable portion of the data grid then the data grid will respond by scrolling in the direction of motion.

How will this feature improve this extension

Currently it is not possible to move a row or column outside of the page view.
This means that you would have to perform potentially many move operations to transport a row or a column a long distance . If on the other hand when you attempted to move a row or column outside of the page the grid began to scroll then we could move a long distance much easier.
