Detailed Description
A ReleaseHeavierToLighterNeighbours is an object used to balance a PartitionedDomain.
It does this by shedding the boundary vertices on the heaviest loaded partition (subdomain).

For numRelease times the Vertices of theWeightedGraph are iterated through.
For each Vertex, \(i\), {releaseBoundary(i, theWeightedGraph, true, factorGreater)} is invoked on the DomainPartitioner. Returns \(0\) if succesfull, otherwise a negative number and a warning message are returned if either no link has been set to the DomainPartitioner or releaseBoundary() returns a negative number.
Implements XC::LoadBalancer.
