Note: karma with dart is still not working because of how `karma-dart` loads `package:…` dependencies. Usage: ``` karma start karma-js.conf.js karma start karma-dart.conf.js ``` Make sure to set `DARTIUM_BIN` env variable. Refactors `js2dart`: - live outside of the traceur module (`tools/js2dart/index.js`) so it can be reused by gulp and karma - automatically build the sources in memory, so that `js2dart` can be used without running `gulp build` first - provide a way to specify the moduleName of a compilation run independently of the input filename. This helps error messages and source maps (not yet enabled) to report the correct file name Changes project setup: - add module `test_lib` that contains the primitives for tests (e.g. `describe`, `it`, …) - clean up some sources that had errors in them - module names in transpiled js and dart files don’t contain `lib`, `test` nor `src` any more (e.g. `di/di`).
