/*
 The purge function takes a reference to a DOM element as an argument. It loops through the element's attributes.
 If it finds any functions, it nulls them out. This breaks the cycle, allowing memory to be reclaimed. It will also look
 at all of the element's descendent elements, and clear out all of their cycles as well. The purge function is harmless
 on Mozilla and Opera. It is essential on IE. The purge function should be called before removing any element, either by
 the removeChild method, or by setting the innerHTML property.
