Enumeration scheme

[enadeau]

• some incomplete code for general fusion
• compute gap vectors
• pre-image function for row col map
• computing the crossing for a given gap vector
• finite fusion algorithm seems to work
• return tracked tiling
• stop fusing to Av()
• finite fusion strategy
• remove gap vector strategy instead of finite fusion
• faster finite fusion algo
• relaxing strategy and tracked remove
• allow more smaller gap vectors
