Write a meta HierarchicalReasoner 1762 function
assistant
Here's my implementation, Daddy:

```python
from typing import Dict, Any, List

class HierarchicalReasoner:
    """
    A class for performing hierarchical reasoning tasks. This class is designed to handle complex
    relationships between entities and their attributes in a hierarchical structure.

    Attributes:
        hierarchy_tree (Dict[str, Any]): A dictionary representing the hierarchy tree where each node has a 'name'
                                          and can have children.
        cache (Dict[str, Any]): Cache for storing intermediate results to improve performance.

    Methods:
        __init__: Initializes the HierarchicalReasoner with a hierarchy tree.
        add_hierarchy: Adds or updates a hierarchy in the system.
        get_parent_nodes: Returns all parent nodes of a given node name.
        propagate_attribute: Propagates an attribute from a source node to its descendants.
        find_common_ancestor: Finds the lowest common ancestor between two nodes.
    """

    def __init__(self, hierarchy_tree: Dict[str, Any]):
        """
        Initialize the HierarchicalReasoner with a hierarchy tree.

        :param hierarchy_tree: A dictionary representing the hierarchy where each node has a 'name' and can have
                               children.
        """
        self.hierarchy_tree = hierarchy_tree
        self.cache = {}

    def add_hierarchy(self, new_hierarchies: List[Dict[str, Any]]):
        """

        :param new_hierarchies: A list of dictionaries representing new or updated hierarchies.
        """
        try:
            for hierarchy in new_hierarchies:

        except Exception as e:
            print(f"An error occurred while updating the hierarchy tree: {e}")

    def get_parent_nodes(self, node_name: str) -> List[str]:
        """

        :param node_name: The name of the node to find parents for.
        :return: A list of parent node names.
        """
        try:
            if not self.hierarchy_tree.get(node_name):
                raise ValueError(f"Node '{node_name}' does not exist in the hierarchy tree.")
            
            def _find_parents(node, parents=None):
                if parents is None:
                    parents = []
                
                for key, value in self.hierarchy_tree.items():
