[GitHub] [tinkerpop] junshiguo opened a new pull request #1372: TINKERPOP-2487 add stdev and percentile steps

junshiguo opened a new pull request #1372:
URL: https://github.com/apache/tinkerpop/pull/1372


   https://issues.apache.org/jira/browse/TINKERPOP-2487
   
   Added two frequently used analytical steps for calculation of standard deviation and percentile value. The example usage is 
   
   ```
   gremlin> g.V().values('ages')
   ==>1
   ==>2
   ==>3
   gremlin> g.V().values('ages').stdev()
   ==>0.816
   gremlin> g.V().values('ages').fold().stdev(Scope.local)
   ==>0.816
   
   gremlin> g.V().values('ages').percentile(50)
   ==>2
   // one percentile, return single value
   gremlin> g.V().values('ages').percentile(0, 100)
   ==>[0: 1, 100: 3]
   // multiple percentiles, return a map
   ```

   Thank you for submitting this for review, though I'd like a bit more time with the dev list discussion before we get to the code.
