• Fixed that fork bug. Just a bit of slop in the Rolon.fork method.
• TRolons now use a custom JSecs CSec which deletes the related JSecs when it is deleted. The idea here is that you may only want a limited amount of history on line. Delete last month's TRolons (which is easy to do, as the journal index orders them chronologically) and the corrisponding JSecs vanish as well.
• And hey, we've got a third of the sample code converted to using RoleML script.
