Adding to __init__.py

Purpose

Make new public APIs available for easy imports.

Rules

• Only import important and relevant classes and functions.
• Do not import everything from a module (e.g., from particula.<area> import *).
• Only include public names (no leading _). These helpers are not intended for public use.
• Keep imports minimal and grouped logically.
• Maintain alphabetical order within groups.

Steps

1. Open particula/<area>/__init__.py.
2. Add under the right section:

from particula.<area> import ClassName, function_name
