Uday,
I don't know if anyone replied, but Nedelec elements of any order exist
in deal.II and are known to work well. There simply is no tutorial
program, but you should be able to piece together what you need from
other tutorial programs.
Feel free to ask on the mailing list in case of concrete questions.
Best
W.
