function Test-TLSConnection {
    <#
    .Synopsis
       Test if TLS Connection can be established.
    .DESCRIPTION
       This function uses System.Net.Sockets.Tcpclient and System.Net.Security.SslStream to connect to a ComputerName and
       authenticate via TLS. This is useful to check if a TLS connection can be established and if the certificate used on
       the remote computer is trusted on the local machine.
       If the connection can be established, the certificate's properties will be output as custom object.
       Optionally the certificate can be downloaded using the -SaveCert switch.
    .EXAMPLE
       Test-TlsConnection -ComputerName www.ntsystems.it
       This example connects to www.ntsystems.it on port 443 (default) and outputs the certificate's properties.
    .EXAMPLE
       Test-TlsConnection -ComputerName sipdir.online.lync.com -Port 5061 -SaveCert
       This example connects to sipdir.online.lync.com on port 5061 and saves the certificate to the temp folder.
