Word phases

This solver does the following phases:

1. Look at all answer possibilities, and finds the word that has the most frequently used letters, given their positions.

For example, the words tesla and slate use the same letters. However, 366 words start with s, and 149 words start with t. Therefore, slate is preferred because it prefers the position of letters.

2. When enough letters are found (3), switch to rating letters non-positionally. Also, do not give any score to letters already known, and try to find remaining letters.

For example, given ?atch is known, it finds a guess word that prefers b, l, p, m, w for batch, patch, match, and watch (ignoring catch and hatch because those letters are already found).

It will suggest the word blimp to match as many of the above as possible.

4. When only a couple words remain, just guess.
