设计Rinex O文件和Rinex N文件读取类，实现对Rinex文件内容的读取和显示.c++,.h.cppmain

下面是一个简单的实现，包含Rinex文件读取类RinexFile和读取示例：

RinexFile.h

#include <fstream>
#include <string>
#include <vector>

    void displayHeader() const;
    void displayObservations() const;
private:

    std::string fileType_;
    std::string programName_;
    std::string date_;
