[FLASH-BUGS] Constant parameters from ignored units override parameters from included units.

[Anshu Dubey]

Aaron,

The setup script cannot arbitrate between units for the initial values of
runtime parameters.
They are picked in the order that setup visits the units. The only place
where the parameter
definitions override other definitions is in the Simulations unit, so the
way to ensure that
you are getting values you want is to include the parameter definition in
you setup directory file.
