Some doubts which are related to the points raised but not following
from them.


1. How are the trans1 and trans2 arrays different?
2. Is the meta-equivalence generation an 8-to-1 affair i.e., one
meta-equivalence class for every 8 equivalence classes?
3. Why doesn't flex generate the minimal DFA? Is it because
backtracking becomes more difficult? Also is the DFA generated a
"suffix DFA"?
