TODO: update web3.js examples ?

uses BN instead of BigNumber
added websockets and new events for these providers (web3.currentProvider.on 'connect', 'end', 'error', 'timeout')
changed web3.eth.sendRawTransaction -> web3.eth.sendSignedTransaction
added web3.eth.subscription
- web3.eth.subscription('logs', {address: '0x12', topics: [], fromBlock: ''}) allows only fromBlock, use web3.eth.getPastLogs for a specifc range of past blocks.
- subscriptions return events like:
  - for "logs": "error", "log", "deleted/reverted"
  - for syncing: "error", "started", "processing", "ended"

This is outdated: The ERC-20 is here: ethereum/EIPs#20

Token

Methods

totalSupply

This method should notify a dapp when the node is syncing (e.g. importing more than 10 blocks), so that dapps can stop asking nodes or process incoming blocks for performance reasons.

We might add fields in the future for state db syncing.

eth_syncing

Returns an object object with data about the sync status.
