For an expression A, the function simple(A) will apply simplification rules to A, and return the resulting expression.

For an array A, the function simple(A) will return an array R with the same dimensions as A. For each element e of A, the corresponding element in R will have the value simple(e).

If the call is assigned to two variables, e and h, then e is assigned the simplified expression or array of expressions, and h is assigned a string representing the simplification method used.  Currently, simplify is the only simplification method used.
