I don't understand what more you could want, really: you're going to
have to supply as input the function expression, the names of the
variables, and the lower- and upper-limit for each.
So the only conceivable simplification I can see is to let the names of
the variables be automatically generated by a defined multipleIntegrate
function you define. But is that a significant saving? You'll already
have to provide 2n + 1 inputs; is adding another n (the names x1, x2,
..., xn) such a big deal?
