Add values to existing map

[flaviu22]

Suppose we have this code:

		fkyaml::node::mapping_type m = { {"foo", false}, {"bar", 3.14} };
		fkyaml::node nw = fkyaml::node::mapping(m);
		nw["employees"] = { { {"name", "Boby"}, {"job", "designer"} }, { {"name", "Nucu"}, {"job", "driver"} } };
		std::cout << nw << std::endl;

Question: how to add to "employees" now values?

employees:
  -
    job: designer
    name: Boby
  -
    job: driver
    name: Nucu

add new name + job value to the existing employees? I know, I can put these values when I initialize the old one, but I am reffering here to a real world situation, when we have some values, like employees, and we want to add more.

Basically all values could be read in C++ data structures, where can be easily modified and then put back to yaml. If you know other methods, please show them up.
