Since visibleRows is listed as an RW "attribute" in the RDoc, I
thought that implied there were methods named "visibleRows" and
visibleRows=" available. That's what I thought I was invoking with
"visibleRows = 5". If those methods existed then Ruby wouldn't have
thought I wanted to initialize a local variable. Right?
Since those accessor methods don't exist, I'll just use "@visibleRows = 5".
