  /**
   * A case-insensitive <code>Map</code>.
   * <p>
   * As entries are added to the map, keys are converted to all lowercase. A new 
   * key is compared to existing keys by comparing <code>newKey.toString().toLower()</code>
   * to the lowercase values in the current <code>KeySet.</code>
   * <p>
   * Null keys are supported.  
   * <p>
   * The <code>keySet()</code> method returns all lowercase keys, or nulls.
   * <p>
   * Example:
   * <pre><code>
   *  Map map = new CaseInsensitiveMap();
   *  map.put("One", "One");
   *  map.put("Two", "Two");
   *  map.put(null, "Three");
   *  map.put("one", "Four");
   * </code></pre>
   * creates a <code>CaseInsensitiveMap</code> with three entries.<br>
   * <code>map.get(null)</code> returns <code>"Three"</code> and <code>map.get("ONE")</code>
   * returns <code>"Four".</code>  The <code>Set</code> returned by
<code>keySet()</code>
   * equals <code>{"one", "two", null}.</code>
