Well, I use a NullFormatter because minor tick labels are turned off
by default.  Otherwise the labels could get quite busy.  Note that
there are 4 players here

  major and minor tick locators  and
  major and minor tick formatters

The minor tick locator is a LogLocator which recognizes the subs --
the minor tick formatter by default is a NullFormatter.  This places
tick lines and empty tick labels.
