First NS Script

<#
Written by David Ott
This script requires the Nitro API for C#.  This is my first powershell script messing with the netscaler.  It will report
all netscalers in HA with status - up or down (if you have HA enabled), all vservers up/down/degraded (if degraded will tell you
which service is down).  All netscaler gateways - up/down, and all ica connections (also whether or not they are using the new
Framehawk protocol - need NS 11.0 62.10 or above)
