First stab at Earthquake Coin: Filling out overview and broad outlines

Things to consider:

1. Most insurance premiums for earthquakes have limits on what can be claimed and this usually requires a trusted 3rd party. We need to determine how to establish claim limits in a decentralized manner. Proof of Stake or Proof of Damage? It's not clear, but it may be possible to pay independent assessors in Earthquake coins for assessing damages.

2. There is software for determining risk. However, it may still be easy to get claim insurance pricing from insurance companies.
