#2918 need easy way to read ascii list of start, stop times to events list

[Jeremy Faden]

Sadie was reading an events list which had just two columns, start and stop. It loads in as stop[start], instead of a bundle of start, stop, and we had to manually do this. The start and stop should be detected and returned in this form, or a URI keyword would tell it to return the form (like eventsListColumn...)

I kludged in a check for start, stop.
