Completed Account Closing

Accounts can now be closed, but only when the balance is 0.
Tested out closing one or both at a time.
Can also open accounts, both or just one.
Verified that the files exist.
Still using a different branch. When I tried to merge the master into
my test branch, something exploded.
Withdrawing works!

The withdraw works. I added the low balance warning for checkings in as
it seemed silly not to do it while I was in there. You’re welcome to
implement it another way (I have it as part of the Account.withdraw()
function )
Deposit Implemented

As far as I tested, it was functional.
Transfer implemented.

Tested one case. I think I could actually do a cross user transfer
without too much fuss. I might try it.
