OK, I've altered the class comment on Interval to indicate that both
integers and fractions are acceptable start, stop, and step values.  I've
also gone through all the senders of #includes:, and it appears that no
existing code will break.  There were only two places that appeared to send
Interval>>includes, those being
HTMLformatter>>select:values:selections:size:multiple: and
HTMLformatter>>swikify:linkhandler:.  Both of these methods should be fine
because the step value on the intervals they're using will be 1.  (Dan,
where's that type inferencer?!? :-).  Comments, as always, are solicited and
welcomed.
