Crystal CLI Generator
TOC
Overview
Put simply, this is a framework that seeks to "objectize" your CLI commands so that you can draw the shape of your commands & command tree in crystal and let the framework make that into an associated command structure.

cmd1 ->
subcmmd1
cmd2 ->
subcmmd2
At a high level the framework (using the class semmantics and macros of crystal) can discover your commands and each's "flags"/arguments via annotations with metadata on what you need to be done for each (static option list, verfiication proc, on_match trigger proc, etc). It's all of this data that allows the framework to serialize them all into a command tree alongside typed flags that allow for us to parse commandline arguments and initialize your command class so that you can pass it around as a data/config object or do actions directly with it.
