/* This is the Profile Item, it should be used for quite a lot of things
 on the profile view. The usage should be pretty simple:

 DiveProfileItem *profile = new DiveProfileItem( DiveDataModel );
 profile->setVerticalAxis( profileYAxis );
 profile->setHorizontalAxis( timeAxis );
 profile->setModel( DiveDataModel );
 profile->setHorizontalDataColumn( DiveDataModel::TIME );
 profile->setVerticalDataColumn( DiveDataModel::DEPTH );
 scene()->addItem(profile);

 This is a generically item and should be used as a base for others, I think...
