v0.9.0

Breaking Changes

• Update dependencies.
  Since hashlink is exposed (through Yaml::Hash) and has been updated from 0.8.4 to 0.9.1, the new version of yaml-rust2 will not link properly if you explicitly rely on hashlink v0.8.
  Existing code with v0.8.4 should still compile fine in v0.9.1 (see hashlink's v0.9.0 changelog).

Bug fixes

• (#37)
  Parse empty scalars as "" instead of "~".

Features

• Add Yaml::is_hash.
• Add better doccomments to the Index and IntoIterator implementations for Yaml to better explain their quirks and design decisions.
