  /**
   *  Creates a Properties object based on an array which contains alternatively
   *  a key and a value.  It is useful for generating default mappings.
   *  For example:
   *  <pre>
   *     String[] properties = { "jspwiki.property1", "value1",
   *                             "jspwiki.property2", "value2 };

   *     Properties props = TextUtil.createPropertes( values );
   *
   *     System.out.println( props.getProperty("jspwiki.property1") );
   *  </pre>
   *  would output "value1".
   *
   *  @param values Alternating key and value pairs.
   *  @return Property object
   *  @see java.util.Properties
   *  @throws IllegalArgumentException if the property array is missing
   *          a value for a key.
   *  @since 2.2.
