Modify how files are binned for manual "day_bin" summaries

[eepeacock]

I recently encountered the issue where I was going to sort 3 files to correspond with a bucket sample that was from hr 2300. The first file after the tower was turned back on was the last file of the day. So, if I took the next 3 files they would be on 2 different days (with <3 files on each day). I then decided to take the first three files from the following day. Subsequently, there was another bucket sample on day 2 of the scenario. So, I have 3 batches of sorted files from 2 different bucket samples that are 23 hours apart and do not want to be binned together.

The solution to both of these problems is to modify they way we bin manual files so that we bin files that are close in time to each other, not necessarily the same Julian day number. The day in question here is day 2016_210. There are actually more than 6 files, because several syringes created 2 files.

separate, but related - What happens when we are summarizing the auto files if 2 files from one syringe are on 2 days?
