I have not added more pattern to the routine integrallookups. The routine
integrallookups is extended to look up an integral on the property list. This
mechanism is similar to the code for getting the derivative of a function.
Furthermore, the code for looking up an integral is not really new but a
generalization of the code used to get the integrals for the logarithmic
function.
