 Tools for building an oracle table

-oracle table for the grammar defined in `grammar.py`.  It's recommended that this be done

-containing the oracle table, complete with imports.
-
-This module can also be used on its own to generate an oracle table on the fly.

-Note that, when run directly, this module will refuse to build an oracle table if ANY of
-the tests defined within the module fail.
+See `grammar` and `build_oracle.sh` for scripts which actually produce python code.  This
+module only produces an oracle table in python, without outputting it.
