// There is a bug https://github.com/cryptocoinjs/btc-transaction/pull/5
// Below works:
// couple of points:
// change the key of scriptPubkey and scriptSig to 'script'. This is something I intend to change
// The bug is at parsing the values. (the values should not be a number and its should be a string)
// e.g. '2000000' rather than 2000000
