found and marked logic bugs in the Board.remove_reflow function
fixed logic bug in Board.remove_reflow
PostIt model is now updated when the DOM PostIt header is clicked on and then clicked off (on 'blur')
eneabled click and blur events for the content of the PostIt, as well.  Now clicking in either the header or the content area will trigger PostIt  model update
refactored the on blur handlers in the Board Controller
removed console log
BUGFIX and REFACTOR: the PostIt.update function wasn't working.  Also, I change the PostIt.id to be a private variable and added a getter for that variable.  All direct calls to PostIt.id throughout the app were updated accordingly"
added a utility/debugging function: post_id_list()
