- Added TestUtils.waitForMqtt

- all tests have fail-fast-behaviour if mqtt broker is not connected
- added some documentation on how to create new test cases
- Base: Fixed logging of writes to output actual values of terminal and topic

- base: fixed bug when multiple dependency definitions have same source (used to generate multiple getter/setter)
- added test case for writing all supported types for default mapping definitions
- inherited attributes for token-attributes are not supported (because no "$token_reset()" is generated by JastAdd)
- added short test descriptions

- 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

- sender/receiver: reuse generated MqttUpdater
- base: added option "--verbose" to print stacktrace if any
- base: move mqtt default port definition to MqttUpdater
- base: add option in MqttUpdater to suppress welcome message
- starter: create 10 joints, use correct mqtt topics

- Copied (and modified) buildSrc from relast. Added compilerLocation property to set a jar to execute.
- Completed example code with computation attributes
- Fixed various bugs in Generation.jadd
- Wrap application of mappings with try/catch and let mapping methods throw Exception
- Add grammar modification for TokenComponent used as source in dependency definition
- Add grammar extension to include relations generated by dependency definitions
- Prepare Ros2Rag.relast for default mappings (not implemented yet)

- 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
