RETM: Add a second automatic column for the place number

I'll probably automate the point assignment here. This is when
TiePlaceAssignment becomes really, really useful.
Add RETM.tieAssign and constructor param
Add ArrayUtils.assignPlacesFromEndTie

This will be used by RETM to populate the # column.
Extract RETM.initializeRow
Document RETM.initializeRow
Add RETM.updateRankColumn
RETM: Call updateRankColumn at end of updateForNewRowCount
