// Async flow


/*
	TODO:
	- this: in all callback and event, it would be nice to bind the current execContext as 'this',
	  so for example each jobs can access to results of others...
	  -> DONE for callback but not for event
	- serialProgress() callback/event that is called for each element, but that respect sequence order 
	  even in parallel mode
	- config(): just set everything in one place?
	- dependenciesTree(): jobs are resolved using a dependencies' tree, that give arguments to transmit
	  from one Async function to another
	- async.Queue: job can be added after exec(), forever, until quit() is called (it needs some brainstorming here),
	  basicaly, some work should be done to move jobs from async.Plan to async.ExecContext
	- caolan/async's: compose(), detect(), filter() ?
	- Real async try/catch/finally, using node's Domain?
	- exportProxy() export a proxy function, if you call the function twice (or more) with the same arguments,
	  the subsequent call will process immediately, replaying all callback immediately and returning,
	  all with the same value
	
	TODO Promises:
	- promise() returning a Promise
	- Promise as a job item, or action function
	
	TODO Doc:
	- Jeu de piste/Organigramme en Markdown, de simples questions proposent des liens en réponse,
	  menant sur d'autres questions avec d'autres liens de réponses, etc... à la fin, on obtient
	  un code d'exemple qui sert de template à copier/coller.
