/**

* adapter pattern

* Purpose:

* to link two systems, that have different interfaces. An adapter defines interfaces that are equal for all linked

* systems and wrap functionality

* Examples:

* - different databases have the same interface to communicate although the underlying systems act differently

* this is a VERY basic example which won't work at all!
