[Cosmo-dev] morse code docs

[Randy Letness]

About the implicit locking on updates:

If we do this, we will also have to implicitly lock the collection on 
updates from CalDAV right?  Otherwise a CalDAV PUT could sneak in some 
data during a morse code update.  This effectively serializes updates to 
collections.  It shouldn't be a big performance hit as there are very 
little simultaneous updates.  Just a change from what the server 
provides now, which is simultaneous updates to a collection assuming the 
updates are to different items.
