VarObject

Provides a variable class with weak type.

1. Support Base Type:

---

	a) long long     (TInteger)
	b) double        (TFloat)
	c) bool          (TBool)
	d) string        (TString)
	e) vector<Var>   (TList)
	f) map<Var, Var> (TDict)

2. Overview:

---

2.1 Structure:

	namespace var {
		class VarObject
		typedef VarObject -> Var

		enum VarType {
			TInteger, TFloat, TBool, TString, TList, TDict
		}
	}

2.2 Overload operator:

support all valid operator overload, eg:

	TInteger: + - * / & | ^ ~ ! >> << ...
	TList: + * ! +=
	...

2.3 Support type transform:

	var::Var a = 3;
	int b = a;
	std::cout << b << std::endl; // 3

2.4 Support List helper

	var::Var a = LIST(2, "abc", true);
	std::cout << a << std::endl; // [2, abc, true]

3. More example:

---

reference test.cpp for more detail. there are some simple example:

	using namespace var;
	int main(void) {
		Var a = 2, b = "abc", c = true, d = 3.4;
		Var dict(TDict);
		dict[a] = 1; dict[b] = 2;
		dict[c] = 3; dict[d] = 4;

		Var e;
		e = a;    cout << e << endl; // 2
		e = b;    cout << e << endl; // abc
		e = c;    cout << e << endl; // true
		e = d;    cout << e << endl; // 3.4
		e = dict; cout << e << endl; // {2:1,abc:2,true:3,3.4:4}

		if(a < 3) {
			cout << "a < 3" << endl; // a < 3
		}
		if(b < "abcd") {
			cout << "b < \"abcd\"" << endl; // b < "abcd"
		}

		return 0;
	}
