!NOTE! Current versions of neo-python/neo-boa does not calculate fees correctly,
deploy with an extra network fee as contract is > 1024 bytes (--fee=0.1, see "Importing")
Testing:
neo> sc build_run 4-domain.py True False False 0710 05 query ["test.com"]
neo> sc build_run 4-domain.py True False False 0710 05 register ["test.com","AK2nJJpJr6o664CWJKi1QRXjqeic2zRp8y"]

neo> sc build_run 4-domain.py True False False 0710 05 transfer ["test.com","AK2nJJpJr6o664CWJKi1QRXjqeic"]
Importing:
neo> sc deploy 4-domain.avm True False False 0710 05 --fee=0.1
