Started multithreading planner.
Added MT planner algorithm.
Updated mt prefix computation algorithm.
Finished MT planning algorithm. Added MT support.
Added mt plan verbose. Checkpoint for milestone SIGSEGV.
Independent milestone buffers for each thread. Working.
Added a random barcode file generator.
Independent cache buffers for each thread.
Changed multithreading plan to subtrie build-query.
Corrected a bug on mt planning algorithm.
No need for mutex on context 0.
New scheduler. Awesome.
