Create a new EthPM registry on chain, and provide a library for integration with EthPM.
Proof of concept; more details and documentation still to come.
Create a new EPM registry on chain using the given from address.
$ epmr new --from "0x1234..." [--host localhost] [--port 8545]
var EthPMRegistry = require("ethpm-registry");
var registry = EthPMRegistry.use(registry_address, from_address, web3_provider);
// Now you can use `registry` as valid registry interface within EthPM.
$ npm test
