Clean user input in Client-Side JS

cleanInput.js

/*

    Depends on JQuery.  By taking input and adding it as text to a DOM-injected div, it forces the content to go
    through JQuery's in-built sanitation.  Rendering it clean of DOM-injection attacks.

    Taken from Socket.io's chat demo source.
