+NIR is simple: it consists of a series of objects that *represent* [NIR structures](primitives).
 In other words, they do not implement the functionality of the nodes, but simply represent the necessary parameters required to *eventually* evaluate the node.
 
 We chose Python because the language is straight-forward, known by most, and has excellent [dataclasses](https://docs.python.org/3/library/dataclasses.html) exactly for our purpose.

 Instantiating the class is simply `MyNIRNode(np.array([...]))`.

+An example of a NIR graph with four nodes: Input, Leaky-Integrator, Affine map, and Output.

 A collection of nodes is a `NIRGraph`, which is, you guessed it, a `NIRNode`.
 But the graph node is special in that it contains a number of named nodes (`.nodes`) and connections between them (`.edges`).
 The nodes are named because we need to uniquely distinguish them from each other, so `.nodes` is actually a dictionary (`Dict[str, NIRNode]`).
