/*
 * Some random notes
 *
 * - for consistency and easier modifications I propose we use a common coding practice Davide... ieally, $event and $EM_Event should always be only variables used to reference an EM_Event object, no others.
 * $EM_Event is a global variable, $event has a local scope. same for $events and $EM_Events, they should be an array of EM_Event objects. what do u think?
 * - Would be cool for functions where we pass a reference for something (event, location, category, etc) it could be either the ID, or the object itself. Makes things flexible, not hard to implement, am doing it already (see EM_Events::get)
