        This Lexer will generate tokens for our string matcher. For example given the expression: (foobar||endsWith(baz) && !qux) we would get the tokens: {LEFT_PAREN, STRING_VALUE("foobar"), OPERATOR_OR("||"), FUNCTION_CALL("endsWith"), LEFT_PAREN("())") STRING_VALUE("baz"), OPERATOR_AND("&&"), OPERATOR_NOT("!"), RIGHT_PAREN(")")}
        Parameters:
        input - The expression to be tokenized
        Throws:
        CompilationException - with clear error message
