## Example

``` javascript

let utxo = require('utxo')

let transactions = {

	"2c20ca6ca3a2af32d3ca0c6c1a60f6d3c00101342620a21f3622fc6faf2ddcda": {

		"inputs": [

			{

				"txId": "xxx ...",

				"vout": 0

			},

			{

				"txId": "xxx ...",

				"vout": 1

			}

		],

		"outputs": [

			{ "script": "..." }

		]

	},

	"bdcdd2fafa1c6c0ac3d23fa2a3ac66cf2263f12a03444310100c3d6c06ac02c3": {

		"inputs": [

			{

				"txId": "2c20ca6ca3a2af32d3ca0c6c1a60f6d3c00101342620a21f3622fc6faf2ddcda"

				"vout": 0

			},

			...

		],

		// etc

	}

}

let unspents = utxo(transactions)

// => [{

//	"txId": "2c20ca6ca3a2af32d3ca0c6c1a60f6d3c00101342620a21f3622fc6faf2ddcda",

//	"vout": 0,

//	"script": "..."

// }, ...]

```

**NOTE**: Any 'double spends' are ignored, with priority given to first-seen.

If `.outputs` is undefined,  an unspent is only `{ txId, vout }`.
