Sorry about the delay in responding, I was away most of the day.
I wrote the tutorial, and looking at it now it could certainly use
more explanation in regards to what module is doing what.
specifying traits => ['Caching'] in your schema applies
to your schema,
which sets the default_cursor_class for your schema to
and also does this:

    if (ref $self->schema->default_resultset_attributes) {
        $self->schema->default_resultset_attributes->{cache_object} =
    } else {
            cache_object => $c->cache
ie sets cache_object ( needed by DBIx::Class::Cursor::Cached )
to  $c->cache, which is provided by Catalyst::Plugin::Cache.
Memcached comes into the picture via the configuration of
Catalyst::Plugin::Cache as you can see in the tutorial.
