/**
 * <p>Reads all key/value pairs in the given map, and 
 * add them to this <code>Map</code>.  Keys are converted to strings
 * using their toString() method, with exception
 * of values being arrays or collections.  In such case, the entry
 * is considered a multi-value one and each value will be converted
 * to individual strings. <code>null</code> keys are ignored.
 * <code>null</code> values are converted to an empty string.</p> 
 * <p>Changes to this instance/*w  w w  .jav a 2s  .com*/
 * won't be reflected in the given <code>Map</code>.  If you want otherwise,
 * use invoke the constructor with a <code>Map</code> argument.</p>
 * 
 * @param map the map containing values to load
