devless_windows_install.ps1

<#
    .SYNOPSIS
    Installs the Devless image and runs it for use on port 4545

    .DESCRIPTION
    This script downloads the devless image on Docker. It does all the checks for exisitng Docker or Devless installs, and
    allows Docker run with the Virtual Machine of your choice on Windows. 

    When you shutdown or restart docker, you will need to start a docker machine and expose devless to a port manually:
    - docker-machine env --shell powershell devless | iex
    - docker run -p 4545:80 eddymens/devless:latest
