            Set

    a Set represents a set of records in the database,
    the records are identified by the query=Query(...) object.
    normally the Set is generated by DAL.__call__(Query(...))

    given a set, for example
       set = db(db.users.name=='Max')
    you can:
       set.update(db.users.name='Massimo')
       set.delete() # all elements in the set
       set.select(orderby=db.users.id, groupby=db.users.name, limitby=(0,10))
    and take subsets:
       subset = set(db.users.id<5)
