Ability to test non-public members

[crookse]

Summary

What: I've found in testing that there is sometimes a need to invoke a non-public member. We should make a function that makes non-public members public.

Why: Sometimes I'll find that I need to test a non-public method or check a non-public property. Adding the ability to "rewire" a class and make its members public would be useful in testing. For example, you could test that a public method calls a protected method. The public method basically covers the protected method, but what if you want to test protected method as its own unit?

Acceptance Criteria

• New Rhum function to make protected members public
• Tests
• Documentation
