//Setup a schema so we can check the arguments to ensure application security
var publicationOptionsSchema = new SimpleSchema({

        type:Number,
        optional:true
    },
    skip:{

       optional:true 
    },
    sort:{
       type:Number,
       optional:true 
    }
});

//Publish friend records with their related user records
Meteor.publish("friends", function (options) {
    if(!this.userId){
        return this.ready();
    }

    options = options || {};

    check(options, publicationOptionsSchema);
