# Note we rely on template inheritance with this MDM Base class i.e. subclasses (e.g.
# HD::MDMPatientsController) can override templates and partials (e.g. add a _filters partial
# or override the _patient partial to replace what is displayed in the table).
# Otherwise the default template location is of course app/views/renalware/mdm_patients.
