	loop(arg1, arg2[, arg3]) == loop.for() == loop.while() == loop.loop()
	
2) Arguments	
	(1) Array or Object 	- require
	(2) process function 	- require
	(3) callback function 	- option

Examples

var loop = require('easy-loop');

var arr = [1,2,3,4,5];
console.log("Case1 Start => Array");
loop(arr, function(key, value, next){
	console.log(key, "=>", value);
	next();	//require
}, function(err){
	console.log("err : ", err);
	console.log("Case 1 result");
});
console.log("Case1 End => Array\n");

/* 결과(Result)
Case1 Start => Array
0 '=>' 1
