PhloxUI Ng2+ Framework

/**
 * <p style="text-indent: 2em;">
 * A <code>ng</code> service interface mainly handles <code>application</code>'s <code>background process</code> executions.
 * Despite the <code>ng</code> framework provides you an <code>asynchronous</code> execution mechanism via <code>Promise</code>
 * or <code>Observer</code> already, this service aims to make all those <code>asynchronous</code> executions easily monitorable
 * by the user. For example, if your <code>application</code> needs to execute multiple <code>asynchronous</code> user's tasks
 * such as saving multiple documents to the backend server at the same time, by using this service, it will keep record of
 * those processes and give you the information about which one is running or is complete at any time.
 * </p>
