Module FlatCurry.Goodies

This library provides selector functions, test and update operations as well as some useful auxiliary functions for FlatCurry data terms. Most of the provided functions are based on general transformation functions that replace constructors with user-defined functions. For recursive datatypes the transformations are defined inductively over the term structure. This is quite usual for transformations on FlatCurry terms, so the provided functions can be used to implement specific transformations without having to explicitly state the recursion. Essentially, the tedious part of such transformations - descend in fairly complex term structures - is abstracted away, which hopefully makes the code more clear and brief.
