Safe operator in python

	# Attempt to create something like a safe operator (?. in js) for Python

	#
	# Solution 1: Overload objects in Python (pollute global name space)
	# Turns out this is not actually possible: https://stackoverflow.com/a/4698550
	# and you have to subclass the main class, and create instances.
	# This is not a great idea since we would have to stop instantiating inbuilt classes
	# and would have weird looking code
	#
	# Solution 2: Possibly create a wrapper class that wraps instances

It's a CommonJS function that checks if two JS Objects are the same, checks nested objects as well

	* Designed to work only if the object is an output of JSON.parse(obj)
	* So Only allowed datatypes for value are: number, string, boolean, object and null
	*/
	"use strict";
	function deepCompare(obj1, obj2) {
	var leftChain, rightChain;
	function compare2Objects(x, y) {
