DBLayer for hibernate should support .get(Class, Serializable) method

Current Situation

The SOS Hibernate DBLayer does not support the get(Class, Serializable) method that is implemented in the hibernateSession.
As the hibernateSession is declared as Object and can be represented by a Session or a stateless Session, there is no getter for the session. Thats why the Dblayer should capsulate the access to the session and should implement the .get(Class, Serializable) method.

Desired Behaviour

The Dblayer should provide the .get(key) method.
