Resizable arrays for dynamic operations on centroids
Renamed node->childNumber to node->nChildren.
To avoid conceptual naming conflict with tree mining and to be consistent

renamed nLambda to lambdaCoeff because it's not an integer
Add frequency coefficients initialization· Add more tests for arrays
Add deletion of centroids having low estimated frequency
tweak test output
added comments to belief_transform.h
