HelpViewer lets you display a series of static HTML pages inside a scroll view.
You can use this to add documentation or help pages to your app.
While HelpViewer uses HTML as source for the pages, it is not meant to be an internet browser. The only intented user interaction is flipping through the pages and opening external links.
For that reason tapping embedded links will open them in Safari or Mail.
This is the second iteration with support for iPad and landscape orientation.
