## ----------------------------------------------------------------------------
## Tests for the $resultset->populate method.
##
## GOALS:  We need to test the method for both void and array context for all
## the following relationship types: belongs_to, has_many.  Additionally we
## need to test each of those for both specified PK's and autogenerated PK's
##
## Also need to test some stuff that should generate errors.
