Retrieve a detection or series of detections from the Family.

.. rubric:: Example

>>> family = Family(
...     template=Template(name='a'), detections=[
...     Detection(template_name='a', detect_time=UTCDateTime(0),
...               no_chans=8, detect_val=4.2, threshold=1.2,
...               typeofdet='corr', threshold_type='MAD',
...               threshold_input=8.0),
...     Detection(template_name='a', detect_time=UTCDateTime(0) + 10,
...               no_chans=8, detect_val=4.5, threshold=1.2,
...               typeofdet='corr', threshold_type='MAD',
...               threshold_input=8.0)])
