function Connect-Qlik {
<#
.SYNOPSIS
  Establishes a session with a Qlik Sense server, other Qlik cmdlets will use this session to invoke commands.
.DESCRIPTION
  Uses the parameter values to establish a new session with a Sense server, if a valid certificate can be found in the Windows certificate store it will be used unless this is overridden by the certificate parameter. If a valid certificate cannot be found Windows authentication will be attempted using the credentials of the user that is running the PowerShell console.
.EXAMPLE
  Connect-Qlik -computername CentralNodeName -username domain\username
