/**
* Wraps information associated with any NFC event.

An {@link NfcEvent} object is usually included in callbacks from
* {@link NfcAdapter}. Check the documentation of the callback to see
* which fields may be set.
*
*
This wrapper object is used (instead of parameters
* in the callback) because it allows new fields to be added without breaking
* API compatibility.
