Fluents merged together and uses two paths (Next and FalseNext), arrows distinguished by the colour (red for falseNext)
execution uses ExecAgent and ExecCircle, execution for a single path implemented
Attempt to improve execution method, cleaning up unused method (setName) in multichild nodes, changed PartialOrderNode's label as AND as requested by client
Refactoring, deleting EmptyNode (Unused)
Refactoring, adding MessageView
messageView introduced on top of canvasView
MessageView displays messages (but does not have a way to discard them)
Messages have close button so that it can be dismissed
if there are more than 2 messages, they are grouped into a list ('more' button)
clicking on 'more' label on message view launches a list of messages in a new window (currently the list is empty)
More button on messageView opens a new window of message list, MessageViewController uses invalidation listener instead of changeListener (binding causes an error otherwise..)
MessageView modified to prevent users from sorting messages
