/* analyze.c


This file contains the routines for finding the rules that
best fit the input address and assigns each element of the
input to the appropriate output field. The process is
essentially one of pattern-matching. The Aho-Corasick algorithm
is used to match rules that map input symbols found by the tokenizer
to output symbols. In the general case a clause tree is built left to
right, matching rules of a particular class, depending on the state.
