"""
Description:
    - This script displays a loading progress bar in the terminal.
    - The progress bar shows the progress of an iterable task with a colored visual representation.
    - The `colorama` module is used to display the bar in green while keeping the percentage data in the default terminal color.

Requirements:
    - Python 3.x
    - The Following Modules:
        - sys
        - time
        - random
        - colorama

Functions:
    - colored_progress_bar(iterable, prefix='', size=42):
        Displays a colored progress bar for an iterable.

Usage:
    - Ensure Python 3.x is installed.
    - Install required modules using pip (if not already installed):

      EXAMPLE:
          pip install colorama

    - Run the script:

      EXAMPLE:
          python loading_bar.py

Additional Notes:
    - The script includes a short delay before exiting to ensure the completion message is visible.
    - The progress bar simulates varying speeds for each step in the progress.
