Description

@thorwhalen

A function that filters out false positives by conditioning detections expecting on
a given expectation of when a second channel should also detect the event.

Example/test

def event_detection_filter(channel_0, channel_1, min_lag, max_lag):
    """A function that filters out false positives by conditioning detections expecting on 
    a given expectation of when a second channel should also detect the event.

    Takes two binary streams ``channel_0`` and ``channel_1`` and returns a stream of 
    ``(channel, index)``
    anytime a detection in one channel is followed by a detection in the other within 
    ``[min_lag, max_lag]`` steps.
    The ``channel`` indicates where the event was first detected and the ``index`` 
    when it happened.
