Version 1.6.0

• Enforce minimum required Ruby version, gem is tested for Ruby '>= 1.9.3'
• Add Rubocop as a development dependency and Hound CI to the workflow since we will use them to detect style guide violations

Version 1.5.5

• Improve code formatting
• Add comprehensive inline documentation (Yard)
• Move documentation from gem to it's own homepage, separate content from it's
  own code e.g. we shouldn't have to update the gem each time we update the
  README. This is also good because the only documentation that should go to
  RubyDoc.info is inline (generated by Yard) which sticks with the version that it
  was written for making it easy for someone to refer to documentation for old
  versions.
• Write tests, coverage now at 98%
