    Generates a unique hash value for a given class.

    This function uses the built-in `hashlib` and `inspect` modules to create a hash value based on the class' methods
    and properties. The members of the class are first sorted to ensure a consistent order, and then the hash object is
    updated with each member's name and signature.

    Parameters:
    - cls (type): The class object to calculate the hash for.

    Returns:
    - str: The generated hexadecimal hash value.
