es6 implementation

[CalebM1987]

This proposed branch implements this package as a modern es6 module. It uses rollup.js to build the distribution file and also converts it to a commonjs es5 module via babel.

This was created because I could not rollup this module in other modules due to circular dependencies and undefined scopes. This branch offers the following improvements:

• rewritten as es6
• distribution file created with rollup resulting in smaller file size
• no more circular dependencies
• named exports for Token, Secret, etc
• added help documentation via jsdoc in the docs folder
• has a new defaults object to store global configurations for secret, ttl, and versionHex, while still exporting a fernet instance to scope Tokens
• renamed test.html to index.html and moved into test folder

tests

All tests are passing in Node, however, I could not get sinon-chai to work in the test html file and mocha causes memory leaks (possibly because of missing sinon-chai?).
