add example survey

these can be found in site/examples. There is a simple unencrypted survey
in "example.json", and an encrypted variant of the same in "encrypted.json".

The key used for encryption can be found in "key.age"; in particular, note
that the passphrase for the encrypted survey is exactly that private key.
