示例1: main
int main() {
PTree<string> pt;
// normal get
string name("Alice");
pt.put("person.name", name);
string nameOut = pt.get("person.name"); // assignment syntax
assert(name == nameOut);
string nameEx(pt.get<string>("person.name")); // explicit syntax, need convert explicitly
assert(name == nameEx);
assert(pt.isValidPath("person.name"));
// const get
const PTree<string>& cpt = pt;
string nameOutC = cpt.get("person.name");
assert(name == nameOutC);
string nameExC;
nameExC = cpt.get<string>("person.name");
assert(name == nameExC);
const string& nameRefC = cpt.get("person.name");
assert(name == nameRefC);
// ref get
string& nameRef = pt.get("person.name");
nameRef = "Bob";
nameOut = pt.get<string>("person.name");
assert(nameRef == nameOut);
// other types
int age = 25;
pt.put("person.age", age);

assert(age == ageOut);
float height = 1.65;
pt.put("person.height", height);

// push as vector
