aod

Create a Python-based task management application called 'On-Demand Tasks' that leverages the 'aod' package to manage tasks dynamically and efficiently. This application should allow users to add tasks with various attributes such as title, description, due date, priority level, and status (e.g., pending, completed). However, instead of loading all attributes at once, the application will use the 'aod' package to load only the necessary data on-demand when accessed. For example, if a user wants to view just the titles of their tasks, the application won't load descriptions or due dates until explicitly requested.

Key Features:
1. Add new tasks with customizable attributes.
2. View tasks by title, which should load other details like description, due date, etc., only when accessed.
3. Update task statuses and attributes dynamically.
4. Utilize 'aod' descriptors to ensure efficient memory usage by deferring the loading of task details until they are needed.
5. Implement a search feature that allows users to find tasks based on specific criteria (e.g., keyword in title, due date range).
6. Provide a summary view that displays high-level information about tasks without loading full details.

The application should demonstrate the flexibility and efficiency of using 'aod' descriptors by showing how it can significantly reduce the amount of data loaded into memory, especially when dealing with a large number of tasks.
