Need a Rails plugin that can also be used as just a jQuery library.

• Written in CoffeeScript
• Has Jasmine tests
• Only requires jQuery — not jQuery UI
• Based off of and styles itself after a single text form field
• Can be downloaded with a minified JS version ready to go
• Rails form helper for creating the field
• SimpleForm detection and helper as well
• Can specify separator characters like Tag-it
