Add Index Page

Update directory structure.

1. If your project root directory is not already your current workig directory, make sure it is.

   cd example-project

2. Create a directory for the documentation itself

   mkdir doc
   cd doc
   mkdir manual

Add *.qdoc file

Create the qdoc file doc/manual/landing-page.qdoc

/*! \page index.html

\title Welcome

Welcome to this simple minimalistic example.

\generatelist classes
*/

Note that the title will be normally used as part of the style. With one esception: If the filename is index.html, q jQuery script of doc-style is going to remove the title from the html page to make it more easy to customize the first page.
