##running pyshbench requires three arguments:

• path to baseline
• path to testcase
• number of test runs for each

For example:

$ pyshbench ~/base ~/test 30
~/test 30: 1388520
Result of  30 runs
Base nps:  1389093.28  stdev:  6041.287972690889
Test nps:  1382020.68  stdev:  6682.202674970863
Speed-up:  -0.5118%
p-value:   0.224

##To Do

• run tasks sequentially when there is just one physical core
