/**
 * This class extends FileTypeMap and provides data typing of files
 * via their file extension. It uses the <code>.mime.types</code> format. <p>
 *
 * <b>MIME types file search order:</b><p>
 * The MimetypesFileTypeMap looks in various places in the user's
 * system for MIME types file entries. When requests are made
 * to search for MIME types in the MimetypesFileTypeMap, it searches  
 * MIME types files in the following order:
 * <ol>
 * <li> Programmatically added entries to the MimetypesFileTypeMap instance.
 * <li> The file <code>.mime.types</code> in the user's home directory.
 * <li> The file <code>mime.types</code> in the Java runtime.
 * <li> The file or resources named <code>META-INF/mime.types</code>.
 * <li> The file or resource named <code>META-INF/mimetypes.default</code>
 * (usually found only in the <code>activation.jar</code> file).
 * </ol>
 * <p>
 * (The current implementation looks for the <code>mime.types</code> file
 * in the Java runtime in the directory <code><i>java.home</i>/conf</code>
 * if it exists, and otherwise in the directory
 * <code><i>java.home</i>/lib</code>, where <i>java.home</i> is the value
 * of the "java.home" System property.  Note that the "conf" directory was
 * introduced in JDK 9.)
 * <p>
 * <b>MIME types file format:</b><p>
 *
 * <code>
 * # comments begin with a '#'<br>
 * # the format is &lt;mime type&gt; &lt;space separated file extensions&gt;<br>
 * # for example:<br>
 * text/plain    txt text TXT<br>
 * # this would map file.txt, file.text, and file.TXT to<br>
 * # the mime type "text/plain"<br>
 * </code>
