Version 0.8.0

• New feature: Load and validate a spec from JS.
  This allows to pre-compile the spec and speed up the CLI processing by ~ 30
  times when deployed. There's no tooling around this yet, but the capability
  is there: Just serialize and store the output of neodoc.parse and later load
  and deserialize it and feed it back to neodoc using neodoc.run(spec).

• New feature: Require flags (ex: '--foo') to be explictly passed, enabling the
  original docopt behaviour. Thanks @robotops. Also see #61. — 8afb9e2
• New feature: Derive the program name from the usage section and fail a parse
  if two usages start off with different program names.

• Improved: Error messages have been improved significantly, telling the user
  more concisely what failed, why it failed and what was expected. Even when
  matching deep into nested groups. Further, error messages are now layed out
  using GNU utils convention, where the program name comes first, then the error
  message, and then the usage overview. Thanks @moll. Also see #62.
