The method in the parser and the class should both be called `DropTable`.
`ifExists` should just be a boolean field.
At some point you might want to add an `OR REPLACE` clause to `CREATE
VIEW`, and add `IF NOT EXISTS` to `CREATE TABLE`. You would not want to rename
those classes, either. Just add a boolean field.
