A consumer of a stub: should be able to stub methods on any Object

A stubbed method on a class: should return the stubbed value; should revert to the original method after each spec; can stub! and mock the same message

A mock: can stub!; can stub! and mock; can stub! and mock the same message

pending example (using pending method): should be reported as "PENDING: for some reason" (PENDING: for some reason)

pending example (with no block): should be reported as "PENDING: Not Yet Implemented" (PENDING: Not Yet Implemented)

pending example (with block for pending): should have a failing block, passed to pending, reported as "PENDING: for some reason" (PENDING: for some reason)
