Circular dependency warnings

[Edouard-chin]

Hi friends 👋 ,

This gem has a few circular dependency issues, Ruby adds a warning about it but this project has disable warning when running the test suite

cli-ui/Rakefile

Line 13 in b34c774

t.warning = false

Projects depending on cli-ui also have to disabled ruby warnings as otherwise the terminal is cluttered with warning.
Basically all file inside the cli/ui/ folder that contain a require 'cli/ui' will throw a circular dependency warning.

Not a breaking deal, but wanted to let you know :).
