Class \Scrivo\SequenceNo
Class to manage the sequence (or order) numbers of various Scrivo entities.
Most Scrivo entitites like pages and lists items can be ordered manually. This is done by setting a sequence number field in the database for say all pages with a common parent.
Note that this ordering has nothing to do with database sequence generation used for generating ids.
Defined in: SequenceNo.php.
