    SelectTranslator needs to support left join
    -------------------------------------------

                     URL: https://issues.apache.org/cayenne/browse/CAY-929
                 Project: Cayenne

    appendTable() in SelectTranslator.java simply appends a list of all tables referenced to the FROM clause. In some cases these tables should instead be added as a join (often a left join). This code needs to allow for that possibility. I can see some trivial ways to do this by hacking this code, but I am not confident of how this might fit into the grand plan of EJBQL and more. Will this code need to accommodate other more complex joins in the future (eg is there ever a need for outer joins?)
