/**
* This is where all of the real work is done.
*
* Special method calls include:
* <ul>
* <li>append_ATTRIBUTENAME($value) (Same as mr_html_tag::prepend_attribute(ATTRIBUTENAME, $value))</li>
* <li>prepend_ATTRIBUTENAME($value) (Same as mr_html_tag::prepend_attribute(ATTRIBUTENAME, $value))</li>
* <li>remove_ATTRIBUTENAME() (Same as mr_html_tag::remove_attribute(ATTRIBUTENAME))</li>
* <li>remove_ATTRIBUTENAME() (Same as mr_html_tag::get_attribute(ATTRIBUTENAME))</li>
* </ul>
*
* How to use:
* <code>
* <?php
* $tag = new mr_html_tag();
* $link = $tag->a('Click me!'); // This will return a new instance
* // mr_html_tag and set the tag='a'
* // and contents='Click me!'
* $link->href('http://foo.bar'); // This will add an attribute to the a
* // tag: href="http://foo.bar" (Same as
* // mr_html_tag::add_attribute()
* $html = $link->close(); // This will close the tag and return the HTML
*
* // All of the above calls can be stringed together using
* // the fluent interface to get the HTML
* $html = $tag->a('Click me!')
* ->href('http://foo.bar')
* ->close();
* ?>
* </code>
