added dozer with needed stuff and  a minimal example: YAMLRootElemet -->...

... TestRoot (in TDefinitions)

-added some jars (dozer needs it)
-added log4j.properties (dozer also needs it)
-added folder dozermappings and mapping file dmYAMLRootElements (fields have to be is-accesible then there is no need for getter and setter)
-create new class TestRoot in model.tosca for test purposes, i am not able to map complete TDefinitons
-added property in YamlRootElement for test purposes
-have to change the type of function and interface because of mapping only testroot at the moment
Jepp wenn man is-accessible auf true setzt, kann man sich die getter und setter sparen :)
