Release 0.0.5

[ripienaar]

I just posted release 0.0.5 and I think the project is now at a point where it's generally useful and have few bugs.

Some highlights since the initial release:

• A new Documentation Site that's prettier and easier to contribute to than a GH wiki
• Many bug fixes - the initial release was non functional
• Homebrew packages
• Exec improvements
  • Environment variables
  • JQ based transforms
• Default values are supported in flags and arguments
• Enums of valid values are supported in flags and arguments

Do let us know how you find it
