Function aw_transform::filter_period_intersect

pub fn filter_period_intersect(
    events: &[Event], 
    filter_events: &[Event]
) -> Vec<Event>

Removes events not intersecting with the provided filter_events

Usually used to filter buckets unaware if the user is making any activity with an bucket which is aware if the user is at the computer or not. For example the events from aw-watcher-window should be called with filter_period_intersect with the "not-afk" events from aw-watcher-afk to give events with durations of only when the user is at the computer.

Example

events:        [a      ][b    ]
filter_events: [     ]   [   ]
output:        [a    ]   [b  ]
