    .SYNOPSIS
    
    Updates the SimplePSLogging Module from GitHub.
    
    .DESCRIPTION
    
    Checks the current releases on GitHub. If there is a new release, downloads the source
    files, copies them to the modules directory, and reloads the current runspace with
    the new module.
    
    .PARAMETER PreRelease
    
    If the latest release is a pre-release version and this switch is included, then
    it will install the pre-release version instead of the most recent production release.
