input_node.py

This module defines the `InputNode` class, a specialized subclass of `PipeNode` that represents an input node
in a data processing pipeline.

An `InputNode` is used to provide initial data into a pipeline, serving as the starting point for data flow.
It does not perform any computation itself but instead holds a value that can be used by other nodes in the
pipeline.

Classes:
    InputNode: A subclass of `PipeNode` designed to serve as an input node in a pipeline.
