Intellij Idea plugin that provides support for http://swagger.io

Based on the sources from the Ansible/YAML plugin, that is in turn based on Neon plugin. It contains a JFlex grammar (neon.flex) that is used to generate Lexer and a hand-written YAML Parser (NeonParser.java) The Lexer is used for highlighting (via FlexAdapter from Intellij). The parser extends Intellij's PsiParser interface and is used for parsing and error highlighting.

Unfortunately a limited subset of YAML functionality is implemented by both Lexer and Parser. This makes it unusable for the Swagger YAML as it requires more than supported currently: for example block-style literals containing Markdown markup are not understood.
