A class to build help for an entire 'G' application.  This class will take in a list of
module paths and build the help for each module.  To build single modules, call this class
with only one module path.
<p>
Note: Help links must not be absolute.  They can be relative, including <code>. and ..</code>
syntax.  Further, they can use the special help system syntax, which is:
<ul>
	<li><code><b>help/topics/</b>topicName/Filename.html</code> for referencing help topic files</li>
 <li><code><b>help/</b>shared/image.png</code> for referencing image files at paths rooted under
                                           the module's root help dir</li>
</ul>
