/*
    Questions:
    * What do you think PFC.props is doing?
	    - Creating a Object with reference parameters, map your keys;
    * What is the concurrency variable good for?
	    - Its as especifique option where limits the number of Promise created.
    * sendOutStatusEmails ignores errors (except for logging them).
      Let's say your task was to make sure the whole function fails as soon sending out any
      email failed. How would you adjust the code?
	    - follows the code:
