Summary:
- Create python classes for ninja vocbulary in `ninja_syntax.py`. These
classes will be serialized to a ninja file
- Create a Writer class in `ninja_writer.py`. The current API supports
adding variables,rules,build actions, etc. This can be extended in the
future (See `test_ninja_writer.py` for examples)
Future Work:
- Update the `Subninja` class once chDir is supported (aosp/2064612)
- Support a width parameter that will be used to wrap long lines of
text. This will improve readability of the generated files
Expected Use Case: Multi-tree build orchestrator
Test: python ./test_ninja_syntax.py
Test: python ./test_ninja_writer.py
