#2209: location manager should use objgroups

[lifflander]

Fixes #2209

• Redesign location manager to use objgroups instead of the hackish method used currently. This reduces a bunch of code and simplifies the interactions.
• Had to order rooted collection construction with this change by reflecting all constructions off of node 0 before constructing them
