Detailed Description

Embodies an update-able, searchable list of unique users This class provides the means to create and maintain a searchable list of unique users.

List entries are pointers to instances of User, keyed by their UserIds. Users may be added and removed from the list individually or the list may be updated by loading it from a data source, such as a file.
