        The executemany() method will execute the operation iterating
        over the list of parameters in seq_params.

        Example: Inserting 3 new employees and their phone number

        data = [
            ('Jane','555-001'),
            ('Joe', '555-001'),
            ('John', '555-003')
            ]
        stmt = "INSERT INTO employees (name, phone) VALUES ('%s','%s)"
        cursor.executemany(stmt, data)

        INSERT statements are optimized by batching the data, that is
        using the MySQL multiple rows syntax.

        Results are discarded! If they are needed, consider looping over
        data using the execute() method.

    Multiple inheritance in python is allowed but care must be taken
    when assuming methods resolution. In the case of multiple
    inheritance, a given attribute is first searched in the current
    class if it's not found then it's searched in the parent classes.
    The parent classes are searched in a left-right fashion and each
    class is searched once.
    Based on python's attribute resolution, in this case, attributes
    are searched as follows:
    1. CMySQLCursorPreparedDict (current class)
    2. CMySQLCursorDict (left parent class)
    3. CMySQLCursorPrepared (right parent class)
    4. CMySQLCursor (base class)
