MiscArrowButton is a recreation of a button from Websters.app
(in Preferences). We are basically just a control that displays a
MiscArrowButtonCell instance.
To get a feel for the arrow button and see what the arrow alignment
settings do, just load up it's palette in IB and try it out. For more
information also check out the documentation for MiscArrowButtonCell
where most of the work is done.

Class initializer. Sets our cell class to be MiscArrowButtonCell.
We don't set our class version because we don't have any instance
variables.
