[release] 1.2.0 🎉

[eonu]

Major changes

• Adds serialization support through the following methods (#63):
  • to_h: Serialize into a Ruby hash (with symbol keys). Accepts a boolean argument, representing whether or not to deep-serialize nested Author and Category objects (defaults to false).
  • as_json: Serialize into a Ruby hash which is also a valid JSON hash.
  • to_json: Serialize into a valid JSON string.
• Remove version filter from query ID list. (#69)

  Previously, all of the following would return the latest paper, 1807.06918v2:

  Arx.get('1807.06918').version #=> 2
  Arx.get('1807.06918v1').version #=> 2
  Arx.get('1807.06918v2').version #=> 2

• Adds ATTRIBUTES constant for Paper, Author and Category entities, as a list of which attributes are available for the entity. (#63)
• Remove key-word arguments from Paper#id and Paper#url. (#70)

  Previously, Paper#id and Paper#url accepted a version key-word argument, which was a boolean variable indicating whether or not to include the version number in the ID or URL.

  This has now been changed to a regular argument, which still defaults to false.

  paper = Arx.get('cond-mat/9609089')
  
  # Old (no longer works)
  paper.id(version: true)
  paper.url(version: true)
  
  # New
  paper.id(true) #=> "cond-mat/9609089v1"
  paper.url(true) #=> "http://arxiv.org/abs/cond-mat/9609089v1"

• Add equality operator (==) to entities. (#68)
