.synopsis
Dependency installer for Mind Reader on Windows.
This sets up a development environment from a BARE windows install.

.description
Install Git for Windows, clone the Mind Reader repository, and install all dependencies.

The script uses winget (A.K.A. "App Installer") to download and install the latest versions of each dependency, defined in winget/dependencies.json

Winget comes preinstalled on Windows 11 (21H2)/10 (21H1) or newer, and can be installed on Windows 10 1704+ through the Windows Store.
If you download Microsoft's developer VM, you have it!
As WinGet is built into Windows, it sidesteps any annoying third-party package managers, and is the lowest common denominator for package installation.

.parameter GitDir
Path to clone the git repo into (Default: $HOME/git/)

.parameter AllowAdministrator
Force-allow running this script as Administrator (not recommended, despite the frequent UAC prompts!)

.parameter NoPrompt
Disable all prompts for user input, and all waiting. (not recommended when combined with AllowAdministrator!)

.parameter ForceInstall
Force installation/upgrade of all modules, even if already present on the system.

.parameter DryRun
Perform a "dry run" of the script, changing directories and running commands, but without modifying anything.

.example
./install-windows.ps1
Perform a default upgrade of all Mind Reader dependencies

.example
./install-windows.ps1 -DryRun
Perform a dry run of the upgrade process, so you can evaluate what commands will be run

.example
./install-windows.ps1 -NoPrompt
Don't prompt for user input when upgrading

.example
./install-windows.ps1 AllowAdministrator
Allow script to run as Administrator
