  * Puts all the keys and values from the specified array into the map.
  * <p>
  * This method is an alternative to the {@link java.util.Map#putAll(java.util.Map)}
  * method and constructors. It allows you to build a map from an object array
  * of various possible styles.
  * <p>
  * If the first entry in the object array implements {@link java.util.Map.Entry}
  * or {@link KeyValue} then the key and value are added from that object.
  * If the first entry in the object array is an object array itself, then
  * it is assumed that index 0 in the sub-array is the key and index 1 is the value.
  * Otherwise, the array is treated as keys and values in alternate indices.
  * <p>
  * For example, to create a color map:
  * <pre>
  * Map colorMap = MapUtils.putAll(new HashMap(), new String[][] {
  *     {"RED", "#FF0000"},
  *     {"GREEN", "#00FF00"},
  *     {"BLUE", "#0000FF"}
  * });
  * </pre>
  * or:
  * <pre>
  * Map colorMap = MapUtils.putAll(new HashMap(), new String[] {
  *     "RED", "#FF0000",
  *     "GREEN", "#00FF00",
  *     "BLUE", "#0000FF"
  * });
  * </pre>
  * or:
  * <pre>
  * Map colorMap = MapUtils.putAll(new HashMap(), new Map.Entry[] {
  *     new DefaultMapEntry("RED", "#FF0000"),
  *     new DefaultMapEntry("GREEN", "#00FF00"),
  *     new DefaultMapEntry("BLUE", "#0000FF")
  * });
  * </pre>
  *
  * @param map  the map to populate, must not be null
  * @param array  an array to populate from, null ignored
