Maven super model

 Inheritance is recursive in Maven but there is a special model which is the implicit super parent in the lineage
 of models you may specify:

 all of the models that you specify are collected to produce a lineage and then the super model is place at
 the top of that lineage to provide default values.

            you are able to specify your own instead of adjusting this text.</description>
