For 2.0.0-rc.1, the official package pulled down from npm has most of the compiled JavaScript files ending with a terminating #sourceMappingURL element bearing what appears to be a path to one of the author's folders. Namely, /usr/local/google/home/mmalerba/flex-layout/src/lib.... This causes most of my tooling (including webpack if an angular-cli project using this flex-layout is later ejected) to throw off a ton of warnings because the sourcemap url is invalid. These warnings also collect in Chrome's developer panel as well when Chrome attempts to load symbols from the sourcemaps.

Based upon other npm packages, it would seem the pathing shouldn't be included in the distribution so that the associated sourcemap provided in the package can be loaded.
