Added chrono header
Updated SimpleBarrier to use C++11 atomics
Part of the KLSM block implementation
Continued implementing KLSM. Not working right now.
working on KLSM
KLSM compiles again, seems to lose tasks sequentially, not tried in parallel yet
KLSM task storage seems to be working now (but without k for now)
Small changes
Debugged KLSM. Still no k-relaxation for KLSM but already competetive performance
Branched off LSMLocalityTaskStorage from KLSM, which has no k-ordering guarantees but very good performance
