   .SYNOPSIS
   Modify the default Label used by Get-PanDevice
   .DESCRIPTION
   Modify the default Label used by Get-PanDevice
 
   PS> Set-PanDeviceLabelDefault -Label 'PCI'
   PS> Get-PanDevice
 
      is functionally the same as
 
   PS> Get-PanDevice -Label 'PCI'
 
   If a default Label is not explicitly set, then the default Label defaults to PanDevice(s) created in the
   current PowerShell session.

   .EXAMPLE
   PS> Get-PanDevice
 
   By default, Get-PanDevice without additional parameters returns PanDevice(s) created in the current PowerShell
   session only.
   .EXAMPLE
   PS> Set-PanDeviceLabelDefault -Label 'PCI'
   PS> Get-PanDevice
 
   Get-PanDevice would return all PanDevice(s) with the 'PCI' label, without having to specify the -Label parameter.
   .EXAMPLE
   PS> Set-PanDeviceLabelDefault -Label 'PCI','us-central'
   PS> Get-PanDevice
 
   Get-PanDevice would return all PanDevice(s) with both 'PCI' and 'us-central' labels. Both labels must match.
   Multiple Label(s) (via array) is a logical AND match when selecting PanDevice(s)
   .EXAMPLE
   PS> Set-PanDeviceLabelDefault -Label $null
   PS> Get-PanDevice
 
   Restores Get-PanDevice default behavior of returning PanDevice(s) created in the current PowerShell session only.
