Classes that deal with finding a list of locations for subscribers. Note these classes return multiple locations for each subscriber, and therefore do not represent a single home location for each subscribers. Mostly they are not used directly, but are called by dailylocations objects, although they can be.
Abstract base class for any class that involves stitching together multiple daily locations (or similar). The class object takes a start and stop datetime, and optionally a list of daily locations objects and returns a day-dated list of locations of each subscriber. This will be the first location in the event of a tie. Subscribers are guaranteed to have a Day Trajectory if they appear in any of the daily_locs objects.
