Hi there, I just came across your project as a new user looking for a declarative config tool compatible with Kong 0.10. Love the idea.

Unfortunately, I am getting errors on the basic operation of trying to to run the "biplane diff" command against a dump of the config. I am totally unfamiliar with Crystal so I'm not sure if this is user error or a bug.

$ ./biplane dump --host localhost --no-https config.yaml
Dumping API to STDOUT
Running against Kong at http://localhost:8001

$ ./biplane diff config.yaml --no-https --host localhost
Running against Kong at http://localhost:8001
Unknown pull kind: NONE (Exception)

Relevant info:
Platform: CentOS Linux 6.8
Biplane: Self-built binary using Crystal 0.15.0. Source cloned from github today 3/14/17.
Kong: 0.10.0, admin service running at http://localhost:8001. No authentication.

I haven't attached the dumped YAML but let me know if that's significant. It contains a bunch of proprietary company info but I can sanitize it if it helps.
