added eventService that will store all lifeEvents across the app
addEvent cleaned up, i want filter to be on its own service
FilterService has method for filtering, works. $scope.addEvent uses that now
figured out why dataContainerTwo initializes with month no matter what. fixed that.
instead of doing a computationally heavy filter every time, addEvent adds event to dataContainerTwo AND allLifeEvents. slight cheat
want to make sure $scope.addEvent affects eventService's data, called allLifeEvents. seems so, by reference
got rid of console.logs, branch to d3 again
Merge branch 'servicerefactor'
