replace the main table of the query, if the table is somewhere within
the given from_obj. this makes it possible to produce custom joins and
outerjoins in queries without the main table getting added twice.
[ticket:315]
- added join_to and outerjoin_to transformative methods to SelectResults,
to build up join/outerjoin conditions based on property names. also
added select_from to explicitly set from_obj parameter.
- factored "results" arrays from the mapper test suite and into the
"tables" mapper
- added "viewonly" param to docs
* Added implicit primary keys to ActiveMapper. Now, if you do not speicfy a
primary key on your objects when declaring them, an Integer primary key
called `id` will automatically be added to your objects for you.
* Commented out a large chunk of the process_relationships function that
should no longer be necessary thanks to some of the deferred mapper
compilation that was added in SQLAlchemy 0.2.3. I left it in the code, but
commented it out just in case this change causes a problem in someone's
else's code and I can put it back in if needed.
