Write NFC Tags

[eucalypto]

As a user I don't want to use a 3rd party app to write the NFC Tag, but I want to conveniently use this app to do it.

This way, the user doesn't have to know or care about how the Tag is written.

• [x] create NdefMessage with including NdefRecords
• [x] activate foreground disptatch to intercept NFC intents

What kind of data to write to the NFC Tag?

I don't want to write user generated data to the TAG for security reasons. This means I have to generate the data myself. This is why I decided to use a UUID for the id of a Category data class item. This UUID is internal and the user doesn't see it unless he exports the data as csv. And I write this very unique UUID to the NFC tag.

Apparently, I really need a separate activity for writing the NFC tag. But I want to use the navigation component to navigate to that activity:
