Todo

• Support configuring defaults & behavior via TOML.
• Built-in daemonizing (update itself using a given command, forever).
• Reverse bargraph direction on LEDs.
• Unit tests.
• Documentation.
• Useful logging in libraries.
• Review API Guidelines Checklist
• Refactor HT16K33 to use an interface.
• HT16K33 should initialize itself before being passed to Bargraph, and Bargraph just verifies that it's usable.

In Progress

• Add --show option for virtual display on the command-line.

Completed

• Refactor ht16k33 library into a separate crate.
• Support OSX compilation.
