Generation of webpack as part of npm publishing step

[abhayks1]

• Pre commit hook is there to generate webpack which generates distribution in dist directory. It should be removed.
• Builds should not be part of the repository, but instead be done in the npm prepack script so that they are built when packaging or publishing.
  Also, a library that is published usually goes into a lib directory, not a dist directory. But that is something we also don’t do everywhere, yet. And any build artifacts should be listed in .gitignore.
