YAML Command v0.1.0

Just released YAML Command v0.1.0. It is a command line tool for working
with YAML files.

As there doesn’t seem to be any other “Shell-based API” for YAML, I
thought
it might be a good idea to devise one.

Appreciate any feedback.

(Note that the very first release of this project was called yc. The
project was renamed for clarity.)
