[Dbix-class] New many_to_many branch changes

[Justin Guenther]

I've just committed some fixes, tests and docs for the many_to_many branch
of DBIx::Class. Basically, this branch adds accessors for adding and
removing related many_to_many objects without mucking around with link table
objects, and includes several tests for this behaviour.

See the POD in Relationship.pm in the branch for more information on these
helper methods. I'd appreciate it if everyone that uses many_to_many could
check it out from the repository and test it with their code. Constructive
criticism of the implementation as well as tests and docs would be greatly
appreciated.

The subversion repository URI for this branch is
http://dev.catalyst.perl.org/repos/bast/branches/DBIx-Class/many_to_many

Much thanks,
