Implement CandidateQueue.cpp

In CandidateQueue.cpp only implement the functions

void CandidateQueue::push_cadidate(Candidate* p)

and string CandidateQueue::Exist(string r)

DO NOT TOUCH this function ->CandidateQueue::CandidateQueue()

For the function void push_cadidate(Candidate* p); // Pushes a pointer to a candidate onto the back of the line (the info of Node is a pointer to Candidate :D ). // update head, tail and count

and for string Exist(string role);

// Check the line and see if there is any candidate with the give role in the line (the line is implemented in linked list) // If there is, return the name of that candidate // If no such candidate exists, returns "".

MUST BE IN C++
