/** Custom loadView method for backwards compatiblity.
 * Unfortunately I've been unable to coerce Xcode 4.4 to generate nib files
 * which are compatible with my trusty iOS 3.0 ipod touch so in order to be
 * fully compatible for all devices we have to build the interface manually in
 * code rather than through the keyed archivers provided by the interface
 * builder.
 *
 * Rather than recreating the user interface manually in code the tool nib2obj
 * was used on the xib file and slightly modified to fit the original property
 * names. Which means here is a lot of garbage you would never write in real
 * life. Please ignore the following "wall of code" for the purposes of
 * learning Nimrod, this is all just because Apple can't be bothered to
 * maintain backwards compatibility properly.
