- changed semantics of ViaTest slightly (setting same value for inputBoth does not change to newly send value as the "FromMqtt-" and "FromRest-" part is not prepended, and therefore it stays the same)

- differentiate between push-send and pull-send

- also fixed bug when using tokens with no type (must be treated implicitly as String)

- rename nonterminal (M)Ros2Rag to (M)RagConnect, and attribute ros2rag to ragconnect
- rename starter to safety
- make receiverstub, receiverstub not depend on safety
- make tests not depend on common (copied proto files)

- supported types: int, short, long, float, double, char, and all their boxed variants, and String
- default mapping definitions are NTAs which get reused for every update definition that needs them
- change generated check for not always apply (case for boxed types)
- cleanup parser

- 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

- allow multiple mappings for update definitions
- in mappings, remove target variable name and prepare for more types, e.g., arrays
- add required option to specify name of root node in Compiler
- copy MqttUpdater in compile step

- 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
