<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
can be treated as if it were any other byte in the same class, and the
result of a search wouldnt change.</p>

<p>This is useful when one needs to know the actual bytes that belong to
an equivalence class. For example, conceptually speaking, accelerating
a DFA state occurs when a state only has a few outgoing transitions.
But in reality, what is required is that there are only a small
number of distinct bytes that can lead to an outgoing transition. The
difference is that any one transition can correspond to an equivalence
class which may contains many bytes. Therefore, DFA state acceleration
considers the actual elements in each equivalence class of each
outgoing transition.</p>
