CalculateSpreadPriority spreads pods by minimizing the number of pods on the same machine with the same labels.

EqualPriority is a prioritizer function that gives an equal weight of one to all nodes.

LeastRequestedPriority is a priority function that favors nodes with fewer requested resources.

MapPodsToMachines obtains a list of pods and pivots that list into a map where the keys are host names and the values are the list of pods running on that host.

HostPriority represents the priority of scheduling to a particular host, lower priority is better.

MinionLister interface represents anything that can list minions for a scheduler.

PodLister interface represents anything that can list pods for a scheduler.

Scheduler is an interface implemented by things that know how to schedule pods onto machines.

FakeMinionLister implements MinionLister on a []string for test purposes.

FakePodLister implements PodLister on an []api.Pods for test purposes.

FitPredicate is a function that indicates if a pod fits into an existing node.
