Detailed Description

Constructor nodes are nodes that do depend on subnodes in order to compute the represented function's result and gradients. They usually provide a way to compose modules, like the gnn_serial : Serial Constructor for Function Composition. or gnn_parallel constructor nodes.

Constructor nodes are the glue of Gradient Backpropagation Machines.

Modules
gnn_parallel : Parallel Node Constructor.
gnn_serial : Serial Constructor for Function Composition.
	A constructor node for node stacking.
