vSwitch Documentation with CDP Information

I was asked today to document all the vSwitches in all of my standalone ESXi host.  Initially I was going to log into each and document everything in excel but I knew there was a more efficient way.  So I started to google and got dozens of sites back and dug through them all and finally found one that worked for me.  I was able to run through one host at a time, but I wanted it to be better.  So I added an import and for each with some squiggly brackets then piped that out to a text file.  See below for full PowerCLI script with my modifications.  Original script before my changes can be found here: http://kunaludapi.blogspot.com
