Tweaked some comments for clarity on the process of creating, initializing, closing, setting ubiquitous and opening a new document. The log below shows a section of one device’s console log in a successful launch/document-creation operation:

	2014-05-09 14:38:46.014 multidocument[3237:60b] Saved new document for creating

	2014-05-09 14:38:47.647 multidocument[3237:60b] Opened created file for reading.

(The other device discovered and opened the document successfully.)
Here’s the tricky timing part:
[1] the local sandbox file existed at the time of openWithCompletionHandler:
[2] at the completion of openWithCompletionHandler:, the file package had been made ubiquitous and had started downloading.
I added the newly created document as a file presenter in -[DocumentsListController(Making) instantiateDocumentFromRecord:]Lines 417-425, todayTrouble in -establishDocument...: the NSLogs show that:• the asynch block in -setUbiquity dispatches• -openWithCompletionHandler: is called• -setUbiquity asynch block completes • -openWithCompletionHandler: handler executes.

Changes for clarity and best practices:
Changed where I invoke -setUbiquitous:,
Added the newly created document as a file presenter.

Changes for clarity and best practices:
Changed where I invoke -setUbiquitous: for clarity. I’m dissatisfied
with that aspect.
Added the newly created document as a file presenter.
