Add Added pagination using the functions (offset, limit)

You can now use the functions offset and limit in order to set the pagination params on find functions. Usage is as follows : 

find : {
    offset: function(){
         return 0;
    },
    limit: function(){
        return 100;
    }
}
can you please split autorouteOptions out into a skip and a limit parameter, and then use these functions on the query object http://mongoosejs.com/docs/api.html#query_Query-skip

also re-enable sort
