Rest

Closes #24

See merge request jastadd/ros2rag!5

Resolve "Cleanup"

Closes #35

See merge request jastadd/ros2rag!4

- finished transformation
- remove indentation from mustache templates
- store YAML in file when --printYaml is given

- 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)

- make compiler jastaddCompliant
- allow multiple input grammars and connect files
- compiler output are (possibly modified) input grammars, and always three files (MqttHandler.jadd, RagConnect.jadd and RagConnect.relast)

- 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)

- Base: inserted DefaultMappings did not account for existing other mappings, but always use type of token
- Base: MqttHandler was not able to have multiple newConnections for the same topic
- Goal: Changed way how last update is handled (now packed into currentStep)
- Goal: Added StartStep
- Goal: Changed wait to be in milliseconds

Resolve "PoC: Use mustache as template engine"

Closes #19

See merge request jastadd/ros2rag!2

- added fail-fast behaviour to mustache (if a name/method can not be resolved)
- enabled logging of mustache (using log4j)

- see #26

- 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

- Starter: Send initial DataConfig
- Starter: Always send complete RobotConfig

- 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

- also try to setup CI (might fail)

- 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)
