<p>
Creates a new expander using <em class="parameter"><code>label</code></em> as the text of the label.
If characters in <em class="parameter"><code>label</code></em> are preceded by an underscore, they are underlined.
If you need a literal underscore character in a label, use '__' (two 
underscores). The first underlined character represents a keyboard 
accelerator called a mnemonic.
Pressing Alt and that key activates the button.</p>
