Creates a Windows Service for Solr 5.3.1 with nssm.exe. Writes stdout and stderr to log. Put this Powershell script in the Solr bin folder with solr.cmd

create-jetty-service.ps1

<#
    create-jetty-service.ps1
    This script needs to be run once, to create the service.
    Service name is mandatory.
    Requires nssm.exe (Non-Sucking Service Manager https://nssm.cc).
    The script assumes it is located in the Solr 5.x \bin folder with solr.cmd.

    N.B. This operation requires elevated permissions. Either run script from Admin version of PS console, or allow to run when it asks.
