function _calendar_limit_nodes in Calendar 5

A function to adjust node values to slice off times before and after the selected view used for calendars that span days, months, or years since the calendar api automatically creates additional calendars for calendars that extend into another time period and the additional calendars will be incomplete (only containing cross-over calendars)
