Don't need to use bash (vs just shell) in some scripts.
Some small readme tweaks.
There are available updates for dependencies.
I need a package to synchronously execute shell commands.
I need a package for project wide config.
I should be able to calculate similarity of Ruby code.

There is also a basic set of tests and coverage tooling for ruby.

Among other things:

* Moved any Ruby test code from top level project to ruby/spec.
* All integrated into the build.
* Documentation updated.
v0.1.1 (ruby)
