o Allocate CEs for each token in the list, based on the total number N of the
largest level difference, and the gap G between baseCE and nextCE at that
level. The relation * between the last item and nextCE is the same as the

o Example: baseCE < a << b <<< q << c < d < e * nextCE(X,1)
? There are 3 primary items: a, d, e. Fit them into the primary gap.
Then fit b and c into the secondary gap between a and d, then fit q
into the tertiary gap between b and c.
o Example: baseCE << b <<< q << c * nextCE(X,2)
? There are 2 secondary items: b, c. Fit them into the secondary gap.
Then fit q into the tertiary gap between b and c.
o When incrementing primary values, we will not cross high byte
boundaries except where there is only a single-byte primary. That is to
ensure that the script reordering will continue to work.
