Packaging hotpot module for better phpdocs documentation structure

Hotpot as a core module should be reviewed for phpdoc generation correct packaging :

all module root level php files should present a :

/**

• file description
• @package mod-hotpot
• @category mod
• @author initial author if known (optional)
• @contributors list of known contributors (optional)
• @license http://www.gnu.org/copyleft/gpl.html GNU Public License (unless other licensing)
  */

/**

• Defines and requires
  */

Subplugins such as hotpot reports types should have an additional @subpackage hotpotreports or something like that tag

/**

• file description
• @package mod-hotpot
• @category mod
• @subpackage hotpotreport (example)
• @author initial author if known (optional)
• @contributors list of known contributors (optional)
• @license http://www.gnu.org/copyleft/gpl.html GNU Public License (unless other licensing)
  */

If some code use MVC pattern, we have added an @usecase tag that could be used to list all handled use cases (UML meaning).

These above docblocks MUST be first block of comment just under <?php opening line.

If the first code construction that follows is a class or a function, it should have its own comment block.

The form :

function afunction($parm){
/// some comments
}

should be deprecated, using phpblocks instead :

/**

• @param type $parm description
  */
  function afunction($parm){
  }

Many thanks for helping improving documentation structure.

Note1 : that all php files should be headed, not only lib ot locallib. This ensures all local function or structure defines will be correctly packed in the right phpdoc subsection.

Note 2 : please all packaging should be at least commited for 1.9 and HEAD branches.
