TimeStep classes not exported?

I know this feature was released just a few days ago so I thought I'd open this issue to help with its progress, although this could just be me overlooking something.

Instantiating a new LSTMTimeStep returns the error below, and brain.recurrent.LSTMTimeStep is undefined. I fixed this by exporting it in the compiled index.js, then instantiating with .default():

// Before

const net = new brain.recurrent.LSTMTimeStep.(options);

// const net = new brain.recurrent.LSTMTimeStep({
//             ^
// TypeError: brain.recurrent.LSTMTimeStep is not a constructor


// After

const net = new brain.recurrent.LSTMTimeStep.default(options);

// dist/index.js
var LSTMTimeStep = require('./dist/recurrent/lstm-time-step');
var brain = {
  crossValidate: crossValidate,
  likely: likely,
  lookup: lookup,
  NeuralNetwork: NeuralNetwork,
  NeuralNetworkGPU: NeuralNetworkGPU,
  TrainStream: TrainStream,
  recurrent: {
    RNN: RNN,
    LSTM: LSTM,
    GRU: GRU,
    LSTMTimeStep: LSTMTimeStep // <---
  },
  utilities: utilities
};

I'm sure that this problem would apply to the other "TimeStep" classes as well, but I've only tested it on RNNTimeStep which does indeed produce the same error.

How are you importing brain?

[torreyleonard]

Using const brain = require('brain.js');

I get the same error, my code is:

const brain = require('brain.js');
const net = new brain.recurrent.LSTMTimeStep();
net.train([1,2,3]);
var output = net.run([1, 2]);  // 3
console.log(output);

error:

const net = new brain.recurrent.LSTMTimeStep();
            ^

TypeError: brain.recurrent.LSTMTimeStep is not a constructor

if I use const brain = require('brain.js').recurrent;
I get this error:

const net = new brain.recurrent.LSTMTimeStep();
                               ^

TypeError: Cannot read property 'LSTMTimeStep' of undefined
