    .SYNOPSIS
        Installation script for FLARE VM.
        ** Only install on a virtual machine! **

    .DESCRIPTION
        Installation script for FLARE VM that leverages Chocolatey and Boxstarter.
        Script verifies minimal settings necessary to install FLARE VM on a virtual machine.
        Script allows users to customize package selection and envrionment variables used in FLARE VM via a GUI before installation begins.
        A CLI-only mode is also available by providing specific command-line arugment switches.

        To execute this script:
          1) Open PowerShell window as administrator
          2) Allow script execution by running command "Set-ExecutionPolicy Unrestricted"
          3) Unblock the install script by running "Unblock-File .\install.ps1"
          4) Execute the script by running ".\install.ps1"

    .PARAMETER password
        Current user password to allow reboot resiliency via Boxstarter. The script prompts for the password if not provided.

    .PARAMETER noPassword
        Switch parameter indicating a password is not needed for reboots.

    .PARAMETER customConfig
        Path to a configuration XML file. May be a file path or URL.

    .PARAMETER noWait
        Switch parameter to skip installation message before installation begins.

    .PARAMETER noGui
        Switch parameter to skip customization GUI.

    .PARAMETER noReboots
        Switch parameter to prevent reboots.

    .PARAMETER noChecks
        Switch parameter to skip validation checks (not recommended).

    .EXAMPLE
        .\install.ps1
