Arkham is a framework for building CLI tools and applications. It provides basic
building blocks for building attractive and smooth CLIs


# CLI Features

## Option Parsing

* Opt/Flag handling for short, long command line options
* Nested subcommands with their own flags
* Opts are hierarchal and can be utilized from parent commands
* Automatic usage details for subcommands and bare execution
* Flags and options can be set via environment variables

## Configuration Handling

Configurations can be loaded from either TOML or JSON files. Configuration files 
can be used to automatically provide values for command line opts or arbitrary
configuration values


## Styling

* Canned helper methods for generating colored and formatted outputs for common
structures: Detail lists, headers, etc.
