Create layer from list of neutrons

[lchild358]

Hello, I think it's helpful to be able to create a layer from a list of neutrons, instead of creating layer only from scratch (giving layer size only), and wish to have:

• the function for connecting two network (output of network 1 is same size with input of network 2) to create a new network (from input of network1 to output of network2)
• the function for combining two or more networks parallelly to create a new network (input = [ input of network1, input of network2, ...] -> output = [ output of network1, output of network2, ... ] Thank you!
