 * Replaced prototypical classes with real ES6 classes
 * Removed `binaryToHex`
 * Removed `hexToBinary`
 * Updated BigNum to 0.13, and dev dependencies to latest
 * Added additional unit tests for coverage
 * Added eslint for code quality checks
 * Updated Travis for modern nodejs LTS releases
 * Updated docs
