-# This is used to classify "powers", that is to say, equations of the form $x^n$, where $n$ is any numeric. It does so by first ensuring that the expression is non-atomic, following that, it checks to see if the first element in the expression is the symbol ~expt~, the second is a variable and the third a numeric.
