def main():
    """
    Main function to initialize and run the CrewAI Machine Learning Assistant.

    This function sets up a machine learning assistant using the Llama 3 model with the ChatGroq API.
    It provides a text-based interface for users to define, assess, and solve machine learning problems
    by interacting with multiple specialized AI agents. The function outputs the results to the console 
    and writes them to a markdown file.

    Steps:
    1. Initialize the ChatGroq API with the specified model and API key.
    2. Display introductory text about the CrewAI Machine Learning Assistant.
    3. Create and configure four AI agents:
        - Problem_Definition_Agent: Clarifies the machine learning problem.
        - Data_Assessment_Agent: Evaluates the quality and suitability of the provided data.
        - Model_Recommendation_Agent: Suggests suitable machine learning models.
        - Starter_Code_Generator_Agent: Generates starter Python code for the project.
    4. Prompt the user to describe their machine learning problem.
    5. Check if a .csv file is available in the current directory and try to read it as a DataFrame.
    6. Define tasks for the agents based on user input and data availability.
    7. Create a Crew instance with the agents and tasks, and run the tasks.
    8. Print the results and write them to an output markdown file.
