Usage

Use the web3c object directly from global namespace:

console.log(web3c); // {cph: .., shh: ...} // it's here!

Set a provider (HttpProvider)

if (typeof web3c !== 'undefined') {
  web3c = new Web3c(web3c.currentProvider);
} else {
  // set the provider you want from Web3c.providers
  web3c = new Web3c(new Web3c.providers.HttpProvider("http://localhost:8545"));
}

Set a provider (HttpProvider using HTTP Basic Authentication)

web3c.setProvider(new web3c.providers.HttpProvider('http://host.url', 0, BasicAuthUsername, BasicAuthPassword));

There you go, now you can use it:

var balance = web3c.cph.getBalance(coinbase);
