ATF tbt BPMs

ATF tbt BPMs. Y.T. Yan. It is not a good idea to relocate some of the existing TBT BPMs from the two arcs to the two Straights. We need to replace some (about every other one, the same as Mark did in the arcs) regular BPMs with TBT BPMs in the Straights and in the no-TBT-BPM ARC locations.
