Nfc test

Added NFC test cases:

Note: Since, with time constraints, did not implement the test spec using the spec methos as suggested by developement team. Hence appended the spec js and spec Html file names with _dev.

Some of the test cases can be fully automated, which will be moved soon to the auto_common_spec. Since auto_common_spec is under preparation.

Please check for the test cases and merge it with the master branch.
