function Export-TNScan {
    <#
    .SYNOPSIS
        Exports a list of scans
 
    .DESCRIPTION
        Exports a list of scans
 
    .PARAMETER SessionObject
        Optional parameter to force using specific SessionObjects. By default, each command will connect to all connected servers that have been connected to using Connect-TNServer
 
    .PARAMETER ScanId
        The ID of the target scan
 
    .PARAMETER Format
        The format of the output. Defaults to PDF. Options include: Nessus, HTML, PDF, CSV, DB
 
    .PARAMETER Path
        The destination file
 
    .PARAMETER PSObject
        Export as PSObject
 
    .PARAMETER Chapter
        The desired chapter. Options include:
        Vuln_Hosts_Summary, Vuln_By_Host, Compliance_Exec, Remediations, Vuln_By_Plugin, Compliance, All
 
    .PARAMETER HistoryID
        The ID of the target history
 
    .PARAMETER Password
        The required password. This is a securestring type. The easiest way to get this is by using (Get-Credential).Password which extracts the password in a secure manner (and does not care about the username.)
 
    .PARAMETER Name
        The name of the target scan
 
    .PARAMETER Credential
        The credential object (from Get-Credential) used to log into the target server. Specifies a user account that has permission to send the request.
 
    .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.
 
    .EXAMPLE
        PS C:\> Export-TNScan -ScanId 10 -Path C:\temp\scan.pdf
 
        Exports scan ID 10 to C:\temp\scan.pdf
 
    .EXAMPLE
        PS C:\> Export-TNScan -ScanId 10 -Type CSV -Path C:\temp\scan.csv -Chapter Compliance
 
        Exports scan ID 10 to C:\temp\scan.pdf with only the Compliance subset
