/**

 There is no support for pod based components in addons as of ember 2.9. Also as ember is moving to https://github.com/emberjs/rfcs/blob/master/text/0143-module-unification.md 
 pods are being discontinued (no longer supported). But for better organization of large in-repo addons pods are a must. 

 This gist provides solution how to use pods based components in in-repo addon. Even components.js based in pods of addon works problem is that template is not
 being compiled. Following adjustments provides also compilation of template. Its only solution I found because of private 
 anonymous function in ember-cli which handles template compilation of addons.

There are times when you prefer a given functionality only happen once, similar to the way you'd use an onload event. This code provides you said functionality:

function once(fn, context) { 
	var result;
