/**
    Enables manual manipulation of an element using 
    Hammer.js multi-touch events to pinch and drag.
    
    This script is little more sophisticated than others I was able to find 
    in that it scales around the centre point of the pinch, and constrains
    the position of the element in both types of operation to keep as much 
    of it inside the container as possible.
    
    Prerequisites: Hammer.js, jQuery or jQLite.
