> Want to have something more usable than SQLTemplate... Its routing defaults, parameter
bindings, etc. etc. are just not that user-friendly. So creating a simpler selecting version
that will internally translate to SQLTemplate.
> Here are construction examples:
> SQLSelect<DataRow> q1 = SQLSelect.dataRowQuery("SELECT * FROM x");
> SQLSelect<Artist> q2 = SQLSelect.query(Artist.class, "SELECT * FROM x"); 
> List<DataRow> l1 = context.select(q1);
> Also use fluent API... some examples from unit tests:
> 1. Complete fluent select:
> List<Artist> result = SQLSelect.query(Artist.class, "SELECT * FROM ARTIST WHERE
ARTIST_NAME = #bind($a)")
>                 .bind("a", "artist3").select(context);
> 2. Selecting a single object:
>  Artist a = SQLSelect.query(Artist.class, "SELECT * FROM ARTIST WHERE ARTIST_NAME = #bind($a)")
>                 .bind("a", "artist3").selectOne(context);
