    onDraw:function(pattern){
        //do something with pattern
    }
});

Mapper

Mapper is way to map indexes of pattern circles with some arbitrary value to make it hard to understand sequence of pattern. 
Mapper can be provided only at the time of initializing PatternLock and can be provided in two way.

As a object
Syntax :

var lock = new PatternLock('#patternHolder',{
    mapper: {1:3,2:1,3:4,4:2,5:9,6:7,7:8,8:5,9:6}
});

As a function
Syntax :

var lock = new PatternLock('#patternHolder',{
    mapper: function(idx){
        return (idx%9) + 1;
    }
});

If you are using mapper, make sure to use same mapper object or function for a user throught the life of pattern.

6. METHODS
