Create Safe classes

[Swader]

Classes right now are just data objects with some decoration. Ideally, they would be able to take the current consolidated state, and throw errors if an illegal op is attempted.

const c = new Consolidator( /** hydrated adapter **/ );
c->consolidate();
const myNFT = new SafeNFT(data, c);
myNFT->send(myAddress, "//Bob"); // Throw New Error("Unable to send NFT, sender does not own it");
