Duck type pandas DataFrame and Series in sim framework

Rather than using isinstance to check if an object is a
DataFrame or Series, support objects that act like them by
checking for presence/absence of attributes.
Ability to disable table copies in sim framework

By default, simulation framework always returns copies of evaluated
tables and their columns, instead of views. Add parameter and
attribute to disable copies where possible. This includes
computed columns but not pandas slices which are always copies.
Added test for copying when enabled and disabled.
