Module pattern 

Pattern inference, matching, and validation.

This module contains the core algorithms for:

• Inference (inferrer): Deriving transformation patterns from before/after example pairs by performing a structural diff of their ASTs.
• Matching (matcher): Finding occurrences of a pattern in arbitrary source code by comparing AST sub-trees.
• Validation (validator): Checking that an inferred pattern is well-formed and likely to produce correct transformations.
