I want to make a few changes to how the numericstepper works. For
instance, when they click the up button and reach the maximum, I want
it to flip down to the minium, and vice versa.

There's just a small bit of code in the checkValidValue() function
that I need to change. However, if I try to override that function I
get the error: "1020: Method marked override must override another
method."

First of all, I don't quite understand why I can override some methods
and not others. And if I can't override that method, what other
options do I have?
