Useless Email Things

Weeding out useless transmissions in a sample base from 280,000 emails via three accounts back to roughly 2006. One downside of my approach is that I'm not capturing a high level count of things before removing, which skews some of the output numbers as we go: if an email is found earlier by a search term in removed, it can't be counted in subsequent searches.
