Removed obsolete dependency to google commons. (Existence of engine already assumable at that place.)
More explicitely checking for a finished process instance in order to avoid checks on stale data.
Protecting constructors of fest assertion entry point classes.
Slightly improved upon error message for missing process engine initialisation.
Allowing to retrieve actual object under test of an assertion.
Allowing to retrieve last TaskAssert used in the specific testing thread.
Allowing to call a TaskAssert from a ProcessInstanceAssert, automatically narrowing down the search for the Task under test to the ProcessInstance under test of the ProcessInstanceAssert.
Providing an initial set of helper methods in order to allow for fluently writable and business readable process engine tests. (For now just integration tested with an example in camunda-bpm-testing-examples.)
Integration test example showing the usage, look and feel of the refactored assertions-only (with-a-few-helpers) fest api.
