* Creates a Properties object based on an array which contains alternatively

* 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.
