   DBIx-Class/0.08/trunk/lib/DBIx/Class/ResultSet.pm
   DBIx-Class/0.08/trunk/lib/DBIx/Class/Schema.pm
   DBIx-Class/0.08/trunk/t/101populate_rs.t
Log:
altered schema->populate so that it is a very thin wrapper on top of resultset->populate and changed resultset_populate so that is accepted both the arrayref of hashes and the arrayref of arrayref style of args.  Documented this, updated the tests a bit to make sure it is all good.
