/**

* This constraint is to make path searches be biased against choosing in the same set polys over and over.
|

|
|
* For Example: if we spawn in place a b c we do not want to spawn there again if there is a place d that matches
|
||
|
|
* our criteria for spawning of guys. We often use this for determining places that No One Has Spawned Near Here Before.
