Provide a shell script for setting up dotfiles automatically

[mu-hun]

When setting up dotfiles on a new device, I've always found that copying and pasting multi-line commands is quite cumbersome.

Many Unix-based tools allow you to automatically install dependencies and configure them to suit your environment. For instance, Oh My Zsh:

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

It would be beneficial to have an automation script that clones this repo and executes all the initial setup commands.

Additionally, if the client is on macOS, we could have a script that automatically installs brew and brew cask apps, sets up iterm2 configurations, and installs app store apps.
