Objects have access to three current types of Notification methods.
Increment and Set both work on the Badge notification type, a small circle with a counter that appears on the Component Tab.
The ShowMessage will display a 'snackbar' style notification inside the Chart.
You access the notifications, using the $emit() method, inside your Component code.
this.$emit('notification', {type: INCREMENT});
this.$emit('notification', {type: SET, count: 3});
this.$emit('notification', {type: SHOW_MESSAGE, message: "This is a message"});
