The Emperor Pinguin has arrived!

This alpha release of vulcan refactors the code to better suit installations on Debian based Linux systems.

In particular it:

• rearranges directories into the more traditional /bin and /libexec directories expected by Linux systems
• pre-compiles and includes yq as part of the Debian package install (yq requires a separate PPA, which cannot be specified in the .deb package as a dependency)
• Introduces a Makefile with targets for building and pushing .deb packages

It also improves the installation experience on OS X and in Docker:

• Introduces a Brewfile to install its brew dependencies
• adds an Ubuntu based Dockerfile
• Introduces a Makefile with targets for building and pushing Docker containers to Docker Hub
• Updates the README with new installation and usage instruction

This release also includes the following fixes:

• LOGLEVEL is not set at the very beginning of execution so that parameter checks can benefit from the log functions
• parse_arg now correctly handles missing positional arguments instead of throwing an indexing error
• Switched to using greadlink to correctly resolve the script directories
• Fixes handling of ~/.*rc files to avoid duplicate insertions
• Fixes calls to custom install scripts so that it uses the shell defined by their shebang
