/*
* equivalence class
* The set of ASCII chars is refined by the sets of chars used by
* the regular expression. The result is a set of equivalence classes:
* disjoint sets of chars, whose union is the ASCII set.
* An eclass struct describes one equivalence class. The structs
* are linked, and headed by `eclasses'.
