make code more beautiful
No, that has been that way since version 0.1.0. Are you serious? Do you think I'd actually change it?
 Also, cluttering up the namespace is grosser to me.
 Also bite me.

The 'Meta class' makes code ugly,would you prepare to make code like this:

class Gym(Model):
    **db_table** = 'gym'
    id   = IntegerField(primary_key=True)
