Marko A. Rodriguez closed TINKERPOP3-601.
-----------------------------------------
    Resolution: Done
      Assignee: Marko A. Rodriguez  (was: Daniel Kuppitz)

This has been completed.

There are two primary benefits for using {{select()}} over {{back()}}.

* {{select()}} will try and NOT use path-calculations if possible in OLTP.
* {{select()}} supports {{by()}} modulation.

Note that all the {{BackTest}} tests were simply cut/paste to {{SelectTest}} and "back" renamed to "select". All tests pass except for on in OTLP (only) that [~dkuppitz] is currently looking into (has to do with nesting selects and related to trying to avoid path calculations -- that reasoning algorithm needs some tweaking it seems).

The documentation has been updated. One less step is one less thing to worry about.

> Consider to get rid of {{.back()}} in favor of {{.select()}}. There's a discussion on the mailing list that points out differences in the behavior of both steps, which should be taken into account since some people may rely on those differences.
