argparser v0.0.1

A simple and small c++ argument parser.

Takes argc and argv as arguments.

argparser::argparser(int argc, char** argv);

enum arg_type{
    A_INT    = 0,
    A_FLOAT  = 1,
    A_DOUBLE = 2,
    A_STRING = 3,
    A_CHAR   = 4,
    A_BOOL   = 5,
    A_NONE   = 6

};

    void add_option(const char* a_name, const char* alt_name, bool *is_parsed, 
                    const char* desc, bool is_required);

Argument type for the type of value parsed. Argument ref reference to where to store the value.

        void add_option(const char* a_name, const char* alt_name, bool *is_parsed, 
                    arg_type type, void* ref, const char* desc,  bool is_required);

Example.

    bool age_parsed   = false;
    bool hello_parsed = false;
    
    int m_age;
    
    argparser m_argparse(argc, argv);

    m_argparse.set_header_info("Simple program v0.0.1.");
    
    m_argparse.set_footer_info("Developed by kenneth buchunju\n"
                               "(C) 2020 <buchunjukenneth@gmail.com>.");

    m_argparse.add_option_group("General options.");
    m_argparse.add_option("hello","hl",&hello_parsed, "A simple hello greeting", false);

    m_argparse.add_option_group("Misc options.");
    m_argparse.add_option("age", "a", &age_parsed, A_INT, (void*)&m_age, "Age of the user",true); 


    m_argparse.parse();
    
    if(age_parsed)
    {
        std::cout << "Your age is: " << m_age << std::endl;
    }
    
    if(hello_parsed)
    {
        std::cout << "Hello there" << std::endl;
