Function Get-DbaLocaleSetting {
    <#
      .SYNOPSIS
      Gets the Locale settings on a computer.
 
      .DESCRIPTION
      Gets the Locale settings on one or more computers.
 
      Requires Local Admin rights on destination computer(s).
 
      .PARAMETER ComputerName
      The SQL Server (or server in general) that you're connecting to. This command handles named instances.
 
      .PARAMETER Credential
      Credential object used to connect to the computer as a different user.
 
      .PARAMETER EnableException
      By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
      This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
      Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.
