It is possible to bind arguments to a variable storing their value, as an
alternative to explicitly calling ``program.get<T>(arg_name)`` or ``program[arg_name]``
This is currently implementeted for variables of type ``bool`` (this also
implicitly calls ``flag()``), ``int``, ``double``, ``std::string`` and
``std::vector<std::string>``. If the argument is not specified in the command
line, the default value (if set) is set into the variable.
```cpp
bool flagvar = false;
program.add_argument("--flagvar").store_into(flagvar);
int intvar = 0;
program.add_argument("--intvar").store_into(intvar);
double doublevar = 0;
program.add_argument("--doublevar").store_into(doublevar);
std::string strvar;
program.add_argument("--strvar").store_into(strvar);
std::vector<std::string> strvar_repeated;
program.add_argument("--strvar-repeated").append().store_into(strvar_repeated);
std::vector<std::string> strvar_multi_valued;
program.add_argument("--strvar-multi-valued").nargs(2).store_into(strvar_multi_valued);
```
