Start "geth" Miner

This section describes how to start the 'geth' miner on a private Ethereum Blockchain.

"geth (Go Ethereum)" allows to operate the built-in miner module with these JavaScript object methods:

miner.start() - Starts the miner 
miner.stop() - Stops the miner
miner.setEtherbase() - Specifies the Etherbase to the miner
miner.setExtra() - Sets a text string to represent the miner
miner.setGasPrice - ? 
miner.getHashrate() - Check to see how fast the miner is running

Let's start the miner with 1 thread now:

> miner.start(1)
Error: etherbase missing: Etherbase must be explicitly specified

Note that the Etherbase, also called coinbase, is the public key of an Ether account, which is needed by the miner to receive mining reward Ether money.

Ok. Let's provide my account address, the public key, to the miner as the "etherbase":

> base = eth.accounts[0]
"0x05d4e1a499775ce9d681abd50bda655c7b5ccb90"

> miner.setEtherbase(base)
true

> miner.start(1)
null

Ok. I think the "miner" is running now. We should see new blocks generated soon.
