Applying the unit conversion

Now that you've written some functions, it's time to apply them! The NASS corn dataset is available, and you can fortify it (jargon for "adding new columns") with metrics areas and yields.

This fortification process can also be turned into a function, so you'll define a function for this, and test it on the NASS wheat dataset.
