Review of std.experimental.testing formal review

the two weeks of the formal review phase are over.
The review thread was very shallow. Dicebot again expressed this 
disaffection with the assert function names 
"should(BeTrue|BeFalse|...)" No agreement could be found. 
Personally, I'm not sure if an agreement can be found, as this is 
more a personal style question rather then technical question.

Some minor comments still need to be addressed:
std.experimental.testing.reflection.TestData fields have no DDoc

I will start the voting thread a week from now.
