Tetra tools

Tools and code libraries for tetromino stackers.

• gomen: very basic web interface for perfect clear solutions
• legal-boards: compute all possible 10-piece perfect clears

• srs-4l: 4-line bitboards, implementing SRS
• compute: multicore utility library

• fumen = 譜面 = ふめん = 2めん
• 2めん + 3 = 5めん
• 5めん = ごめん = gomen

Sorry. It's a terrible pun. Hopefully I come up with another name.
