        .SYNOPSIS
            New-TBOrg will create TFS/VSTS Project and Team structure from an associated CSV or XML file.
        .DESCRIPTION
            This function creates Teams with associated security groups, iterations, area, repos, and dashboards(future release). By specifying
            a template file, TFS/VSTS admins can use automation to manage large projects. This function can be run to also reset permissions and
            settins on current projects created by this tool. Define your template and never manually create a team again.
        .EXAMPLE
            New-TBOrg -ProjectName "MyTestProject" -ProjectDescription "The best project ever." -ImportFile C:\MyTFSOrgImport.csv -NewProject
            This command creates a new Project named MyTestProject and creates teams defined in the CSV file name MyTFSOrgImport.csv. CSV File
            import will create groups based on TeamCode and no custom names.
        .EXAMPLE
            New-TBOrg -ProjectName "MyTestProject" -ProjectDescription "The best project ever." -ImportFile C:\MyTFSOrgImport.xml -NewProject
            This command creates a new Project named MyTestProject and creates teams defined in the xml file name MyTFSOrgImport.xml. The xml file can
            define advanced settings for permissions and custom group names.
        .EXAMPLE
            New-TBOrg -ProjectName "MyTestProject" -XMLAdvancedImportFile C:\MyTFSOrgImport.xml -GenerateImportFile
            This command creates a new Project named MyTestProject and creates teams defined in the CSV file name MyTFSOrgImport.csv
