Did some putzing with global relabeling to try to integrate it with the new initial labeling schemes.  This is still in progress. Fixed bugs with maxInitialLabel which cause early termination and set First relabel to take into account relabels that happen during initializaiton. Added in code to do globalRelabel as distance to sink, but #ifdef'ed it out due to assertion violations - primarily with cher. Tweaked relabelBranch due to bugs with nodes that have infinite distance - we want to be able to disable pruning nodes with infinite distance. Removed some debug output, cleaned up comments.
