- Compiler: replace existing files if needed
- Renamed Aspect.jadd to Generation.jadd and fill it with content
- Missing: Generation of dependency relation, and change of token names in grammar

- renamed scanner and parser to Ros2Rag{Scanner,Parser}
- changed Compiler to not use System.exit throwing exceptions instead and have a dedicated run method
- implemented ASTNode.globallyResolveTokenComponentByToken and UpdateDefinition.resolveMappingByToken

- changed compiler to accept two additional required parameters "inputGrammar" and "inputRos2Rag"
- update ros2rag grammar according to latest draft
- begin with parser (missing resolving amongst others)
- parsing in test kind of fails because of leading comment

- added relations that would be generated
- added methods for convenience dependency specification
- added parameter "writeCurrentValue" to connect methods of write definitions (not always wanted, thus optional)
- split method to update token-NTA in update (which now flushes) and write (using saved last value)
- cleanup of unused code

- Introduce type IntPosition, and token-nta _AppropriateSpeed
- Using aspect for generated outputs now (because we are extending Joint and EndEffector inherits from Joint, not possible with using GeneratedJoint anymore)
- GeneratedJoint and GeneratedRobotArm left for reference (not used anymore)

- Example: add integer token to test. using the position would mix both operators (which should be possible, but is the difficult case)
- Example: add could-be-generated methods for the robot arm
- Example: testing to set the token in Main
- Example: added publish method to generic MqttUpdater
- Example: copied protobuf definition for robotconfig

- Example: use Position class created by protobuf, use a wrapper in grammar instead for lists
- Example: manually extend Joint, currently only one connect
- Example: added generic MqttUpdater handling subscriptions
- Example: added some glue code, that would be generated normally
- Example: copied protobuf definition for linkstate
- SenderStub: new module with main to construct minimal linkstate and send it via mqtt
