Summary: @public Fixes [#393](https://github.com/facebook/react-native/issues/393). Currently the transformer assumes line-preserving compilers and defaults to a super-fast source map generation process. However, we need to support compilers that aren't preserving lines. I had feared this wuold slow down the server but I came about a little known peace of the spec that defines an "indexed source map" just for the purpose of concating files: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit Test Plan: 1. runJestTests.sh 2. run server and click around example apps 3. add a custom transporter like babel 4. add a custom file and a debugger statement 5. debug in chrome and make sure it works redbox still works
