The sites in a Roster can be broken down into categories which are made available to other plugins.
A blank line of markup starts a new line in the Roster.
Any line of markup that is not recognized as a site or special command can become a category name.
The category will include all sites on the current and subsequent Roster display lines until another category name is encountered.
Category names can appear before, after or even between sites on a line. Remember blank lines of markup start new lines in the Roster display.
