/**
 * A class to handle most of the parsing operations of a doc comment element.
 *
 * Extending classes should implement the getSubElements method to return
 * a list of elements that the doc comment element contains, in the order that
 * they appear in the element. For example a function parameter element has a
 * type, a variable name and a comment. It should therefore implement the method
 * as follows:
 *
 * <code>
 *    protected function getSubElements()
 *    {
 *        return array(
 *                'type',
 *                'variable',
 *                'comment',
 *               );
 *    }
 * </code>
 *
 * The processSubElement will be called for each of the sub elements to allow
 * the extending class to process them. So for the parameter element we would
 * have:
 *
 * <code>
 *    protected function processSubElement($name, $content, $whitespaceBefore)
 *    {
 *        if ($name === 'type') {
 *            echo 'The name of the variable was '.$content;
 *        }
 *        // Process other tags.
 *    }
 * </code>
