//
// Pretty print accounts summary. Constant function, does not consume gas. No unlocks needed.
//
// Usage:
//	Save to file, e.g. '/tmp/checkAllBalances.js'
//	From the geth console, do: loadScript('/tmp/checkAllBalances.js');
//	Execute with checkAllBalances()
//

// For the price feed ABI, see http://forum.ethereum.org/discussion/3417/ask-%CE%9E-community-what-do-you-think-of-our-new-smart-contract-pricefeed
