This will install a minion locally on windows. Option parameters will accept version, minion id, master id, and a flag for stopping and setting the salt-minion service to manual for local testing.  Passing in a verbose flag will increase logging. Finally, help is displayed via 
man ./bootstrap-salt.ps1
help ./bootstrap-salt.ps1
