removeEvents *1.2*
==================
Removes events from the calendar.
.fullCalendar( 'removeEvents' [, *idOrFilter* ] )
If `idOrFilter` is omitted, *all* events are removed.
If `idOrFilter` is an ID, all events with the same ID will be removed.
`idOrFilter` may also be a filter function that accepts one [Event Object]()
argument and returns `true` if it should be removed.
