Save Collect times

Set the dopSaveCollect function to default to dop.epoch.times for the
latency/time variable
There were also some changes to the dopCalcSummary function from
earlier with Heather was asking questions about adding a t-test. I
haven’t implemented these in the save function yet… haven’t had a
chance to figure out how to accept her push request… or something! One
day - but I’m on holiday…
