Lexicographical Indexing of Transaction Inputs and Outputs.

See [BIP69](https://github.com/bitcoin/bips/blob/master/bip-0069.mediawiki).

\* *Works only with node.js 0.11 or greater (because require Buffer.compare)*

## Example

``` javascript

var bitcoinjs = require('bitcoinjs-lib')

var bip69 = require('bip69')

var inputs = [{

	"txId": "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",

	"vout": 0

}, ...]

var outputs = [{

	"script": new Buffer("76a9145be32612930b8323add2212a4ec03c1562084f8488ac", "hex"),

	"value": 40000000000

}, ...]

// ...

var sortedInputs = bip69.sortInputs(inputs)

var sortedOutputs = bip69.sortOutputs(outputs)

var txb = new bitcoinjs.TransactionBuilder()

sortedInputs.forEach(function (input) {

	txb.addInput(input.txId, input.vout)

})

sortedOutputs.forEach(function (output) {

	txb.addOutput(bitcoinjs.Script.fromBuffer(output.script), output.value)

})

// ... and so on

```
