dyAE code has errors

[jhljx]

In the dyAE.py file, the code in line 113 should be

x_diff = Subtract()([x_hat, x_pred])

rather than

x_diff = Subtract()([x_hat, x_in])

Also, in dyAE program, batch_generator_dynae function didn't use lookback information, which didn't match the algorithm proposed in the dyngraph2vec paper.
