Get / Set Object

I changed the way a getter and setter transformer is defined. Passing an array like that is confusing so I changed it to an object. Example:

Old way:

    var yesNoTransformer = [function(value) {
        return value === "yes";
    }, function(value) {
        return (value) ? "yes" : "no";
    }];

New way:

    var yesNoTransformer = {
    set: function(value) {
        return value === "yes";
    }, 
    get: function(value) {
        return (value) ? "yes" : "no";
    }
    };
