RFR: 8283712 : Create a manual test framework class

[lawrence.andrews]

We need a common manual test framework code that can be shared across all the client manual test. This framework class should have the following
1) Frame which contains test instruction .
2) Pass & Fail button so that user can mark the test pass or fail
3) Upon failing the test user should be able to elaborate why the test failed and this can be added to the test failure. 
4) Disposing of all the frames.
