I'm using the example from above.
I would like to use the above method to scroll the calendar to the 12th hour of the day.
I thought I might need to use `this.calendar.scrollToHour(12)`, however I get an error that it is not a function.
Interestingly, from the VueJS example, `this.calendar.message("Welcome!")` also throws an error:
[Vue warn]: Error in mounted hook: "TypeError: this.calendar.message is not a function"
What is the proper way to use scrollToHour with Vue?
