    <#
    .SYNOPSIS

    .EXAMPLE
    $session = New-TssSession -SecretServer https://tenant.secretservercloud.com -Credential $ssCred
    New-TssDistributedEngineSite -TssSession $session -SiteName 'New Site 1'

    Create a new Site in SSC subscription called "New Site 1"

    .EXAMPLE
    $session = New-TssSession -SecretServer https://tenant.secretservercloud.com -Credential $ssCred
    New-TssDistributedEngineSite -TssSession $session -SiteName 'New Site 2' -Active:$false

    Create a new Site in SSC subscription called "New Site 2" and disable it upon creation.

    .EXAMPLE
    $session = New-TssSession -SecretServer https://vault.local/SecretServer -Credential $ssCred
    New-TssDistributedEngineSite -TssSession $session -SiteName 'Dev Network' -SiteConnector 4

    Create a new Site called "Dev Network", assigning Site Connector 4
