+   .Synopsis
+    Creates a new .iso file
+   .Description
+    The New-IsoFile cmdlet creates a new .iso file containing content from chosen folders
+   .Example
+    New-IsoFile "c:\tools","c:Downloads\utils"
+    This command creates a .iso file in $env:temp folder (default location) that contains c:\tools and c:\downloads\utils folders. The folders themselves are included at the root of the .iso image.
+   .Example
+    New-IsoFile -FromClipboard -Verbose
+    Before running this command, select and copy (Ctrl-C) files/folders in Explorer first.
+   .Example
+    dir c:\WinPE | New-IsoFile -Path c:\temp\WinPE.iso -BootFile "${env:ProgramFiles(x86)}\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\amd64\Oscdimg\efisys.bin" -Media DVDPLUSR -Title "WinPE"
+    This command creates a bootable .iso file containing the content from c:\WinPE folder, but the folder itself isn't included. Boot file etfsboot.com can be found in Windows ADK. Refer to IMAPI_MEDIA_PHYSICAL_TYPE enumeration for possible media types: http://msdn.microsoft.com/en-us/library/windows/desktop/aa366217(v=vs.85).aspx
