**square_integrals**,
a Python code which
returns the exact value of the integral of any monomial
over the interior of the unit square or symmetric unit square in 2D.

The interior of the unit square in 2D is defined by

0 <= X <= 1, 0 <= Y <= 1.

The interior of the symmetric unit square in 2D is defined by

-1 <= X <= 1, -1 <= Y <= 1.

The integrands are all of the form

f(x,y) = x^e1 * y^e2where the exponents are nonnegative integers.
