test against different use cases

[kathryn-baker]

The best way to identify bugs, missing features and usability of the code is to test it against different use cases. We have the following cases in mind:

• CPS crates
• polylithic
• OPCuA
• MOXA

Any issues arising from these test cases should be logged and addressed either in p4p_ext or p4p_for_isis.
