    A simple fact-checking system that verifies if a given statement is true or false.
    The checker has limited reasoning sophistication, focusing on basic pattern matching and keyword analysis.

    Args:
        keywords (List[str]): List of important keywords that must be present for the statement to be considered true.
        phrase_patterns (Optional[List[str]]): Optional list of regex patterns representing phrases that should match for the statement to be true. Default is None.
    
    Attributes:
        keywords (List[str]): The list of required keywords.
        phrase_patterns (Optional[List[str]]): The optional list of regex patterns.
