/**
* Some specific (certified) apps need to get access to certain Firefox Accounts
* functionality that allows them to manage accounts (this is mostly sign up,
* sign in, logout and delete) and get information about the currently existing
* ones.
*
* This service listens for requests coming from these apps, triggers the
* appropriate Fx Accounts flows and send reponses back to the UI.
*
* The communication mechanism is based in mozFxAccountsContentEvent (for
* messages coming from the UI) and mozFxAccountsChromeEvent (for messages
* sent from the chrome side) custom events.
