Test-Latency

A need arose to determine the latency to a few different nodes and act on that matter. Someone on the internet had almost already written all the Powershell code I wanted. However the code was primarily focused on outputting the results in a CSV-file and not actually using the result in the best aus online casino code afterwards.

Therefore I have re-written this function to output an object instead.

 Uses Test-Connection and determines latency to a host
 .DESCRIPTION

 [CmdletBinding()]
 param(
 [Parameter(Mandatory=$False, ValueFromPipeline=$true,
 HelpMessage="Hostnames or IP-Address seperated by commas")]

 Begin {}
 Process
 { 

 $ComputerNames = $ComputerNames.split(",")
