Overview

Normally we handle numbers by use of a refinement on Fixnum However, in some cases, we may have the fixnum as the start of an expression. In this case, we have a problem, because Fixnum#+ is not overloaded to return a DiceNode. In this case, we must use this, a NumberNode. NumberNodes wrap a number.
