Commit ID	348cd5ed74e808733545c392d1bd80965a379617
Author	Jerry Donald Watson

Simple razoring: depth 1 only, no distinction between PV / NonPV We simplify the razoring logic by applying it to all nodes at depth 1 only. An added advantage is that only one razor margin is needed now, and we treat PV and Non-PV nodes in the same manner. How to continue? - There may be some conditions in which depth 2 razoring is beneficial. - We can see whether the razor margin can be tuned, perhaps even with a different value for PV nodes. - Perhaps we can unify the treatment of PV and Non-PV nodes in other parts of the search as well.
