Executes a \"cycle\" of this screen.
* The concept of \"cycle\" is no longer accurate, and is misleading.
this function will not return.
New threaded implementation:
* Checks if self.path is a valid path, using `os.path.exists`
* Assigns a new Queue to `queue_of_valid_files`
* Appends a new `FileScannerThread` object to a list of threads
* `start()`s the `FileScannerThread`
* `FileScannerThread` will put paths in the queue as valid
file paths are found
* `clear_screen()`s
* Gets a file from `queue_of_valid_files`, removing item from queue
* While nextFile (empty sequences are false)
* As long as there is something in the queue - that is, as long
as `queue.queue.get()` is able to get an object from (the)
`queue_of_valid_files`, this test evaluates True.
* I imagine that this behaves unpredictably given a computer
with __REALLY__ slow I/O
* Opens `nextFile` with handle-auto-closing `with` statement and
`typing_print()`s it
* Clears screen if `self.cleanup_per_file`
* Puts `nextFile` ON the queue
* Because `queue_of_valid_files.get()` REMOVES a file path
from the queue, `_run_cycle()` will never reach that path
again, and eventually will exhaust the queue
(failing silently, with a blank screen)
* A static blank screen is the antithesis of a screensaver
* Therefore, `queue_of_valid_files.put(nextFile)` puts the file
path at the last spot in the queue
* Finally, another call to `queue_of_valid_files.get()` sets up
the next iteration in the while loop.
