Changes

# update an object and perform calculations after it has been saved (i.e. support ticket subjects, say you want to combine an autonumber field with the L1 subject but, when you first create the L1, the autonumber hasn't been reserved and stored yet until after you save).

# affect objects at different levels (i.e. a L2 formula can be used to update a L1, an L1 formula can be used to aggregate its contacts).

# easily perform difficult calculations with MySQL functionality and avoid heavy scripting (i.e. perform business day calculations).
