Get-ProcessPerfCounter.ps1

1. <# 
2. .SYNOPSIS 
3.     This script creates a process, then displays some performance counters. 
4. .DESCRIPTION 
5.     This script calls System.Diagnostics.Process's Start static 
6.     method to create a process.  Then it displays perf stats till the
7.     process is stopped. Then it prints final stats out.
