# Optionally for each possible letter to choose from
# A hash describing the count and position possibilities
# For instance:
    e => {
        '03' => 47,
        '1'   => 99
    },
# Means of the remaining candidate words, the letter 'e'
# Comes in two flavors, either only in the first position
# Or in positions 0 and 3.  So if e was chosen and correct
# Either 47 words would remain or 99 - max being 99
