Right click to mount/unmount VHD in Windows 7 or Windows Server 2008 R2

Tool to mount / unmount VHDs by right clicking on a VHD file. This new tool will work on Windows 7 or Windows Server 2008 R2 systems with or without Hyper-V role. This one uses diskpart commands available within this new OS and hence there is no dependency on Hyper-V WMI interfaces. So, you can use this new script only if your system has Windows 7 or Windows Server 2008 R2.
