anyone who knows better, please feel free to correct me. in objective-c
(and, i would assume, java) a static class can only be instantiated once.
static variables within a class (again, in objective-c) are class variables
(shared by every instance of the class) and are not inherited. a final class
is one which has been frozen. there is really no difference between a final
class and any other class, other than the fact that subclassing it is not
allowed.
(waiting for someone smart to enumerate my mistakes in the above paragraph)
