Native implementation roadmap

This is a crude list of the things that need to occur to swap out the Ruby implementation in favour of a completely native one:

v1.0.0 (MVP)

• Remove old Ruby specific matchers
• Replace Ruby Mock Server with dynamic library
• Generate v2 compatible pact files, with parity of previous matching capabilities
• Remove Mock Server from daemon code
• Wire into PactClient and Pact structs
• Add all of the body matchers supported by the JVM
• Replace Ruby Verifier with dynamic library (WIP)
• Remove remaining Ruby stuff from daemon
• Remove all existing Daemon and CLI code
• Ensure matcher error messages are formatted and readable
• Create local Docker setup to test multi-OS capability
• Update examples with latest DSL
• Update documentation (pact.io, README and doc.go)

<--- feature parity = 1.0.0 release

v1.1.0

• Manage provider states through Golang Pact API hooks, instead of HTTP endpoints
• Add all of the matchers supported by the JVM, including Paths/Headers and other body matchers
• Add support for XML
• Allow root level matchers as per JVM (including arrays)

v1.2.0

• Allow one-way messages to be Pact tested (think message queues)
• Handle v1, v1.1, v2 and v3 specifications better
