<#
    .SYNOPSIS
        Stops synchronization of local folder (with subfolders) with Media Library (matching structure) on a remote Sitecore instance

    .DESCRIPTION
        The script allows you to work with SXA Themes in a more comfortable way.
        You can need specify the instance hostname, a folder to watch and the location of your Theme in Media Library 
        in the variables directly below and run the script that will monitor and upload your changes.

        The script requires that SPE Remoting is deployed and enabled on the Sitecore Server.
        The script requires that SPE Remoting PowerShell Module is installed on your local machine.
                
        The following endpoints must be enabled:
            - remoting
            - mediaUpload

		The script requires the same xml config that was profided for Start-MediaSyncWatcher
