Temporary Hash Registrar
========================

This is a simplified version of a hash registrar. It is purporsefully limited:
names cannot be six letters or shorter, new auctions will stop after 4 years.

The plan is to test the basic features and then move to a new contract in at most
2 years, when some sort of renewal mechanism will be enabled.
