Aliases with sdsql and simpler CTAS

First, we just put up a new build of sdsql.  Go get it or the last thing here will not work.   SQL is a great and verbose language so there's many ways to shorten what we have to type.  As simple as a view or saving a script to call later with @/path/to/sessions.sql  SDSQL is taking it a step further and we added aliases to the tool.  Almost as if right on queue, John asked if we could add them.
