Support units specified in defined variables from Silo

[aowen87]

I am not sure we support units for expressions in VisIt. However, Silo's DBPutDefvars call allows callers to define units for the expressions. A user has requested these be visible in VisIt just as units on ordinary variables are. This may or may not be a lot of work. We don't support units through expressions right now. We probably ought to. But, all that is needed to satisfy this is to ensure that whatever units the Silo file said should be associated with the RESULT of an expression should just be bound to them. So, it doesn't really require that expressions support units, just bind any units specified by the database upon completing the expression.
