<p>This is used in a DFA to reduce the size of the transition table. This can

have a particularly large impact not only on the total size of a dense DFA,

but also on compile times.</p>

<p>The essential idea here is that the alphabet of a DFA is shrunk from the

usual 256 distinct byte values down to a set of equivalence classes. The

guarantee you get is that any byte belonging to the same equivalence class
