Edit Loaner Info

Created method to edit loaner info by modifying the checkout.php and
update_out.inc.php.
Added loaner info table

Changed headers to increase one size, and added a table to loaner info
display.  Didn't like it, so I commented it out and left the original.
Leaving just in case.
Changed loaner list to radio buttons

Instead of two hrefs in the menu, created one menu and toggled the view
using radio buttons.  Found a JS function to grab $_GET variables using
regex and put in a condition statement based upon that.
