OrmSkeleton upgrade method to be commented

[WebEP]

Could you add a comment to the method.upgrade.php so that people be very carefull before using this as an example?

Something like:

//Drop all the tables and recreate them
// NEVER DO LIKE THIS IN YOUR MODULES, SEE HOW TO HANDLE AN UPGRADE, USING SWITCH
$entities = MyAutoload::getAllInstances($this->GetName(), $this->getName());
foreach($entities as $anEntity) {
OrmCore::dropTable($anEntity);
OrmCore::createTable($anEntity);
}
