+This module defines the AIPlugIn abstract base class for the OnAIR Platform.
+
+The AIPlugIn class serves as a foundation for all AI plugins in the OnAIR system.
+It establishes standards and structures for compliance that must be adhered to by
+the four imported plugin types: Knowledge Representation, Learner, Planner, or
+Complex Reasoner.
+
+This abstract base class defines the basic structure and required methods that
+all AI plugins must implement.
