=head1 DESCRIPTION
=head2 new
-Arguments: schema_class (scalar), inflect_plural, inflect_singular
-
-C<$schema_class> should be a schema class name, where the source
-classes have already been set up and registered. Column info, primary
-key, and unique constraints will be drawn from this schema for all
-of the existing source monikers.
-
-Options inflect_plural and inflect_singular are optional, and are better documented
-in L<DBIx::Class::Schema::Loader::Base>.
