In this problem, you will implement the function
FindPersonById(const std::vector<Person>& people, unsigned int id). This function will search people for a Person with id. If the person exists, simply return people.at(loc) where loc is the index of the Person in people. If a Person with id is not found in people, report this to the caller by throwing an std::runtime_error with the message Invalid id number.
