Preparing for Release

- Remove `./dist/` builds from release; For node.js module,
  the main `index.js` file is more preferable due to readable
  debugging output.

- Remove empty scripts

- Remove usage prototypes.

- Get rid of all the jsdoc (javadoc) from source code; They do
  not contribute meaningfully to the project.

TODO: Polish the README.md into an API reference.
Ignore the ./dist/ folder; That's only for web modules.
