(AR):
1. Removed faulty code from "all_knobs.cc" and "all_knobs.h" which incorrectly attempted to read a new parameter from 'params.in' to decide whether to use pseudo-LRU or TAP-BIP as the insertion policy.
2. Cleaned up code in "cache.cc" and "cache.h"
Merge branch 'master' of github.com:matt-welch/macsim_bip
