Solidify event file formats with pipelines
Created on September 28, 2017. Copied from redmine (https://bugs.ligo.org/redmine/issues/5917)
Based on the discussion that Alex and I had today, we decided we should try to clarify how each pipeline will be submitting event files. E.g., file type, file format, required parameters, optional parameters, etc. Ideally, we could get a short document from each pipeline on this so that we have a written record to go off of. This is not a top priority but would be quite useful going into O3.
