A way of letting you keep up with changes to files and folders in a user's Dropbox.

@param string|null $cursor
If this is the first time you're calling this, pass in `null`.  Otherwise,
pass in whatever cursor was returned by the previous call.

@param string|null $pathPrefix
If `null`, you'll get results for the entire folder (either the user's
entire Dropbox or your App Folder).  If you set `$path_prefix` to
"/Photos/Vacation", you'll only get results for that path and any files and folders
under it.

@return array
A <a href="https://www.dropbox.com/developers/core/docs#delta">delta page</a>, which
contains a list of changes to apply along with a new "cursor" that should be passed into
future `getDelta` calls.  If the "reset" field is `true`, you
should clear your local state before applying the changes.  If the "has_more" field is
`true`, call `getDelta` immediately to get more results, otherwise
wait a while (at least 5 minutes) before calling `getDelta` again.

@throws Exception
