/*
ProtoJmfr - Handles the request to add or remove items from the jmfr cart
Because we cant know if a item is already in the jmfr cart in the DOM we handle this
on the server side.
 
When a user clicks on any jmfr button the the products list or any list where jmfr is located
a onclick event send a toogle request via ajax to the jmfrview.php
the jmfrview.php then returns a state to the ProtoJmfr
 
The different States is
added = the products was sucessfully added to the jmfr view
removed = the product was already in the jmfrview and because of that it was removed
full = the jmfrview limit is reached and products needs to be removed from the jmfrview
