Winston Chang	6923a11038	Don't add class attribute for internal-facing classes ... The class attribute is unneded for these classes, and this improves performance.	2014-08-28 20:21:05 -05:00

Joe Cheng	5f61267f75	Allow integers or numerics for priority	2013-04-19 15:42:18 -07:00
Joe Cheng	94ee42cebb	Add priority levels to observers ... Observers can now take priority levels, which allow the user to control the order of execution. Note that reactive expressions do not have priority levels; since they are lazily evaluated, it wouldn't make any sense to speak of priorities. Another commit will be needed to add an API for changing the priorities of outputs (probably in outputOptions?).	2013-04-19 10:34:34 -07:00
