Two output node should give error

[srivastava9]

While making a neural network architecture, It should give an error when one tries to make two output node.

Right now it does not give any error.

@orionpax00 Need your update on this one also :)

@srivastava9 , I think its okay to have multiple input and output nodes(as mentioned in #115). Francois Chollet, who is the creator of Keras, writes about them in his book Deep Learning with Python (Specifically Chapter 7: Advanced deep-learning best practices).

Moreover, Inception Networks and Residual Connections are examples of such non linear networks.

True, But I guess we are not making such advance model right now,Anyway when it goes to backend it only accepts one input and output model right now.Therefore I opened this issue. @ivantha @orionpax00 need your suggestion :)
