  Phil Gillis supplied us with the complex functions used for the cxp package. Most of the functions presented here are modified versions of those. Stu Feldman provided us with valuable advice and some functions. Doug McIlroy's constructive comments led to a major rewrite. Eric Grosse suggested the FFT function as an example.
