made changes to the way VMC supplies walkers to DMC.
added option to switch RNGs
Did a thuril test of the normalize population function. It works as intended
Population normalization is achieved by maximizing the amount of nodes with ceiled average rather than floored. Result should be that no node should carry more than 1 more walker than the lowest populated one. Previously the maximum was n_nodes-1.
Fixed up the stdout in DMC
