/**
* Notification building class for conversation messages.
*
* Message Notifications are built in several stages with several utility classes.
* 1) Perform a database query and fill a data structure with information on messages and
* conversations which need to be notified.
* 2) Based on the data structure choose an appropriate NotificationState subclass to
* represent all the notifications.
* -- For one or more messages in one conversation: MultiMessageNotificationState.
* -- For multiple messages in multiple conversations: MultiConversationNotificationState
*
* A three level structure is used to coalesce the data from the database. From bottom to top:
* 1) NotificationLineInfo - A single message that needs to be notified.
* 2) ConversationLineInfo - A list of NotificationLineInfo in a single conversation.
* 3) ConversationInfoList - A list of ConversationLineInfo and the total number of messages.
*
* The createConversationInfoList function performs the query and creates the data structure.
