- unit-of-work does a better check for "orphaned" objects that are
...
part of a "delete-orphan" cascade, for certain conditions where the
parent isnt available to cascade from.
- it is now invalid to declare a self-referential relationship with
"delete-orphan" (as the abovementioned check would make them impossible
to save)
- improved the check for objects being part of a session when the
unit of work seeks to flush() them as part of a relationship..

late compilation of mappers. now you can create mappers in any order, and they will compile their internal state when first used in a query or flush operation (or their props or 'c'/'columns' attributes are used). includes various cleanups and fixes in support of the change, including some unit test changes, additional unit tests.

added explicit "session" argument to get(), select_whereclause in mapper, as well as throughout the call-chain for those. lazy loader honors the "session" of the parent object, + added simple unit test

a cool example that illustrates vertical table storage, and objects that automatically configure themselves for this type of storage

got some support for mapping to a select that only selects some of the columns of an underlying table

added 'noninherited table' prop to mapper indicating the "lead" table, in the case of
...
inheritance. relations now create priamry/secondary joins against that lead table. if you want to create it against
an inherited table, use explicit join conditions.
added 'correlate' argument to CompoundSelect to get polymorph example working again.

added backref() function, allows the creation of a backref where you also send keyword arguments that will be placed on the relation

a mapper with inheritance will place itself as "dependent" on the inherited mapper; even though this is not usually needed, it allows certain exotic combinations of mapper setups to work (i.e. the one in the polymorph example)

added new 'polymorphic' example. still trying to understand it :) .

fixes to relation to enable it to locate "direction" more consistently with inheritance relationships
more tweaks to parenthesizing subqueries, unions, etc.
