SQLAlchemy CREATE and DROP

---

• metadata.create_all(engine, checkfirst=True|False) emits CREATE statement for all tables.
• table.create(engine, checkfirst=False|True) emits CREATE statement for a single table.
• metadata.drop_all(engine, checkfirst=True|False) emits DROPT statement for all the tables.
• table.drop(engine, checkfirst=False|True) emits DROPT statement for a single table.

metada can create (or drop) the tables in the correct order to maintain the dependencies.
