added a view helper to render the no records available output
Fixed a bug when calling the event after deleting a feed record
Merge branch 'feature/add_view_helper' into develop

was always being linked to, instead of the add new feed route. This
corrects that behaviour.
Updated the documentation in a number of the core classes
