function Get-SslCertificateBinding

    <#
    .SYNOPSIS
    Gets the SSL certificate bindings on this computer.
    
    .DESCRIPTION
    Windows binds SSL certificates to an IP addresses/port combination. This function gets all the SSL bindings on this computer, or a binding for a specific IP/port, or $null if one doesn't exist. The bindings are returned as `Carbon.Certificates.SslCertificateBinding` objects.
     
    .OUTPUTS
    Carbon.Certificates.SslCertificateBinding.
 
    .EXAMPLE
    > Get-SslCertificateBinding
     
    Gets all the SSL certificate bindings on the local computer.
 
    .EXAMPLE
    > Get-SslCertificateBinding -IPAddress 42.37.80.47 -Port 443
    
    Gets the SSL certificate bound to 42.37.80.47, port 443.
    
    .EXAMPLE
    > Get-SslCertificateBinding -Port 443
    
    Gets the default SSL certificate bound to ALL the computer's IP addresses on port 443.
