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 Change-Id: I90c7ee69ddeb7c20c3fd4fca5a911dddbf2253bd
