Changed PolymakeTransformer interface to Transformer interface. Transformer extends Future.
Removed needless files of type Result because of new software design decision.
Schlegel interface and TestSchlegel created
Maser is correct. Merge conflict
 use java 1.7
finished Transformer interface
implementation of AbstractTransformer.
merge
modifications for new Transformer interface so that there are no compiler errors
Merge branch 'master' into gui
Adding picture of the event system of our meeting 15.12.13
Merge branch 'master' of github.com:Ryugoron/point-groups
First draft fo the event system, alex wants to do further work
Event-system: added getEventType to EventHandler
Added EventDispatcher#remove method
Renamed HasHandlers into HasEventHandlers and put into gui.event root
* New EventListener, because an EventHandler had previously two tasks,
  declare a `onEvent` method and deligate a event of this type to the
  `onEvent` method, now the EventHandler deligates an event to the
  EventListener and the EventListener declares the `onEvent` method
* added EventHandler#dispatch and fixed EventDispatcher#dispatch
Added a TestCase for the event flow in the event system
Reworked the event structures as i described during the session. The need to change the eventDispatcher when adding eventtypes has been removed, there is one generic addHandler method. also the listener/handler doubling has been removed -- i still dont know what they were for. handler and listener are synonyms i think. Since an event GETS dispatched, it is now a method of the specific event class. there is no need that event handlers (those who want to receive events) need to know how to dispatch events, this is centralized in the eventdispatcher. since firing an event and dispatching it are two different things, the HasEventHandlers interface was corrected, dispatching in EventDispather is now done is a type safe way, types get checked during add-method. the HasXHandler interfaces are now optional for abstraction of classes that allow to add handlers dynamically.
corrected modified of internal fireEvent method of dispatcher. adjusted testcase for implementation
