/**
 * Simplified method to open a Java InputStream.
 * <p>/*from  w w w  . ja  v a  2 s. c om*/
 * This method is useful if you want to easily open things from the data folder or from a URL, but want an
 * InputStream object so that you can use other Java methods to take more control of how the stream is read.
 * </p>
 * <p>
 * If the requested item doesn't exist, null is returned. This will also check to see if the user is asking for a
 * file whose name isn't properly capitalized. It is strongly recommended that libraries use this method to open
 * data files, so that the loading sequence is handled in the same way.
 * </p>
 * 
 * @param theFilename The filename passed in can be:
 *        <ul>
 *        <li>An URL, for instance openStream("http://creativecomputing.cc/");</li>
 *        <li>A file in the application's data folder</li>
 *        <li>Another file to be opened locally</li>
 *        </ul>
