#state ⇒ Object

Intentionally did not use a state machine for this for a few reasons 1) I’m not all that happy with transitions 2) Can’t find another state machine that I like and is worth the cost of switching to 3) This works just fine. I prefer calculating state on the fly here because we’re couning the memberships

on this member anyway

4) Determining a lapsed or past member is a touch more complicated than it sounds

A lapsed member is a member with lapsed memberships *and no current memberships*
It's that last bit that makes grabbing all last members quite difficult in SQL

Note that this method uses the cached values for current_memberships, lapsed_memberships, and past_memberships
