/**
* Abstraction for datastream validators.
*
* Classes extended from DatastreamValidator don't require much to be useful.
* They accept an IslandoraFedoraObject and a DSID to perform assertions on;
* all you have to do is place a series of functions inside the extended class
* using the naming convention assertThing(); each of these functions should
* ideally assert one thing and one thing only (for simplicity's sake), and
* should generate either a pass or a fail message by calling addPass() or
* addFail(). That's it, really; they don't have to return any values, as
* addPass() and addFail() just add messages to the overall pass/fail array.
*
* As long as you use those rules and naming conventions, all the magic is done
* when you instantiate the new datastream validator object.
*
* The IslandoraWebTestCase::assertDatastreams() function accepts paired DSIDs
* and datastream validator names in order to do the rest of the work. It grabs
* all the test results using getPasses() and getFails() and transforms those
* into something that DrupalWebTestCase can use.

/**
* Constructs and ingests a Fedora object and datastream(s) via tuque.
*
* All keys inside the parameter arrays for this function are optional. it
* can be run simply by calling the method with no arguments.
*
* If your test case supports logged in Drupal users, IslandoraTestUtilities
* can be instantiated with $params['logged_in_user'] as that user object, and
* this method will set the owner of the ingested object as that user by
* default.
*
* @param array $properties
* An array containing object information using these keys:
* 'label' - The object label; randomized if not set.
* 'pid' - 'namespace:pid', or just 'namespace' to generate the suffix.
* 'models' - An array that can contain multiple content model PIDs, or a
* string containing a single content model PID.
* 'owner' - The object's owner. Defaults to the currently logged-in user,
* if available. It is recommended to set this to a value that can be found
* in $this->users; otherwise, this object will have to be manually deleted.
* 'parent' - The PID of the parent collection.
* @param array $datastreams
* An array containing zero or more datastream arrays that use the keys:
* 'dsid' - the datastream ID; randomized if not set.
* 'path' - The path to the file to use; defaults to fixtures/test.jpg.
* 'control_group' - The single-letter control group identifier.
* 'mimetype' - The datastream's mimetype.
*
* @return bool|array
* FALSE if the object ingest failed, or the object array if successful.
