/*
A debug utility that allows to trace out properties in an object 
and its each __proto__ in its __proto__ chain respectively.

Usage 1:

Object.prototype.x = 8;
myObj = {x : 5};
traceProtoChain(myObj);

The output would be:

<In the object>
    x : (number) 5
<In the object.__proto__>
    x : (number) 8


Usage 2:

traceProtoChain(myMC, true);
//'true' exposes the built-in hidden properties.
