/** The class AddressBook implements the base class for the TDE addressbook.
* \par Overview
* It
* is used by the KabAPI to make the interface to kab files available to
* application programmers. <BR>
* Unlike in the first kab version, the configuration file and the data file are
* different objects of QConfigDB. This way, the data file is no more limited
* to the one in the users KDE directory, multiple files may be used. Different
* instances of the program may use different data files. Read-only addressbook
* files are possible. <BR>
* Only one configuration file per user is used, it is <BR>
* <TT> ~/.trinity/share/apps/kab/kab.config </TT> <BR>
* A standard user file will automatically be created as <BR>
* <TT> ~/.trinity/share/apps/kab/addressbook.kab </TT> <BR>
* File changes are watched by the program, so every instance will automatically
* update its database on a change of the opened file.
*
* \par The TDE addressbook database system
* kab manages entries in address databases based on a key system where the
* program assigns keys to added entries. These keys are not reused in one file,
* so API users can rely on a key to be unique and identifying until the entry
* is deleted by the user (this is a change to kab 1 that reused freed entry
* keys). Of course, in different files a key might be used twice. <BR>
* The keys are objects of the type KabKey and define the section in the
* addressbook database where the entry is stored (see QConfigDB
* reference). Keys invalidate on file changes, so keep track of the
* signal ::changed. <BR>
* kab watches file changes. If the opened file changes on disk, it is
* automatically reloaded and ::changed() is emitted.
*
* \par The users standard personal information database
* kab assumes that it is able to read and write the users standard database.
* This way, the kab application itselfes and applications using the KabAPI can
* rely on the possibility to add entries to this database (from a browser, for
* example). Usually, this file is opened automatically by the constructor.
* If - for what reason ever - the file cannot be either created or read, kab
* will still start up, but no database operation will work until the user
* opened a file. In this case, the method ::getState will return
* ::PermDenied. In general it is a good idea to check the return value of the
* ::getState method before using KabAPI operations.
*
* \par The mirror map
* The entries are stored in the QConfigDB object ::data which represents the
* currently opened file. In every file there is a section with the name
* <TT> entries </TT> that contains a subsection for every entry. The name of
* the subsection is the key of the entry. <BR>
* When retrieving the sections, they are ordered alphabetically by their keys.
* This is not what users expect, since the keys show the insertion order of
* the entries, not more and not less. Additionally the displaying order should
* be configurable. <BR>
* That is why kab uses a STL map to map its entry keys to user
* (at least programmer...) defined descriptors. Usually, the descriptors are
* created as a combination of the entry data, and then displayed in aphabetical
* order in the selector combobox. This map is called the mirror map throughout
* the documentation. It is created or updated every time the database changes.
* Thus the way to find a special entry is: <OL>
* <LI> the user selects an item in the selector combo box, returning its
* index, </LI>
* <LI> the index is used to find the key of the entry in the mirror map, </LI>
* <LI> and finally the entry is retrieved by its key from the database. </LI>
* </OL>
* To modify the sorting order, the way to create the entry descriptors in the
* mirror map nedds to be changed.
*
* \par The view
* If you display an AddressBook object (that is a derived TQFrame),
* it may show an entry
* of the database that you might select. The entry you hand over to the method
* ::displayEntry does not need to be contained in the currently loaded file.
* This way you may integrate views of
* the users addressbook database in your own application as a simple widget
* type. To allow the user to
* navigate through the database, you might want to show kab's own toolbar in
* your mainwindow (or whereever). (The toolbar is not implemented by now). <BR>
* Some parts of the AddressBook widget are \e interactive, that means they are
* displayed as transparent KURLLabels that react when the user clicks on it.
* These interactive parts have to be enabled by calling setInteractiveMode().

/** Each entry in a loaded database has its own ::Entry object.
*
* \par The structure of the address database
* As you might have read, kab uses the QConfigDB class to manage its
* data files. This class is intended to handle hierarchical structures.
* Thus, kab is able to create human readable but still deep and complex
* data files. This paragraph describes the overall structure of the
* files, the next two deal with special parts of it. <BR>
* First of all, kab II data files (that usually end with \c .kab, while in
* kab 1 the fixed file name was \c addressbook.database) have two main
* sections (see the documentation of the QConfigDB and Section classes),
* one is called \c config, it contains different file specific
* configuration settings like the last displayed entry, and one section
* called \c entries that in turn contains a subsection for each entry in
* the database file. The keys of this subsections are the literal strings
* that are used in the KabKey class in the member KabKey::key. Each entry
* subsection has some key-value-pairs described below and another
* subsection "addresses" with one or more addresses in it. See the
* following example for a kab II data file (without any key-value-pairs):
* <BR> <PRE>
* [config]
* [END]
* [entries]
* [1] (the first entry with literal key "1")
* [addresses]
* [1] (the first address, addresses are enumerated)
* [END]
* [2] (the second address)
* [END]
* ... (more addresses may follow)
* [END]
* [END]
* [2] (the second entry)
* [addresses]
* [1]
* [END]
* [END]
* [END]
* ... (more entries may follow)
* [END] </PRE> <BR>
*
* \par The fields an entry contains
* An entry contains all settings that are expected to be unique for all
* addresses directly as key-value-pairs. Everything that is part of a
* specific address of this person is part of an object of the member list
* \c addresses referenced in the next paragraph. <BR>
* The keys defined directly in the entry sections are: <DL>
* <DT>title<DT><DD> The title of that person. </DD>
* <DT>rank<DT><DD>A possible military rank of that person. </DD>
* <DT>fn<DT><DD>The formatted name. If it is not empty, it replaces the
* standard combination of the other name fields in the address
* display. </DD>
* <DT>nameprefix<DT><DD>A possible name prefix. </DD>
* <DT>firstname<DT><DD>The first name. </DD>
* <DT>middlename<DT><DD>The middle name. </DD>
* <DT>lastname<DT><DD>The last name. </DD>
* <DT>birthday<DT><DD>The birthday (a TQDate). </DD>
* <DT>comment<DT><DD>A free form comment. </DD>
* <DT>talk<DT><DD>The talk addresses (a string list). </DD>
* <DT>emails<DT><DD>The email addresses (a string list). </DD>
* <DT>keywords<DT><DD>A list of free-form keywords. </DD>
* <DT>telephone<DT><DD>A list of telephone numbers in a special format. </DD>
* <DT>URLs<DT><DD>A list of internet addresses. </DD>
* <DT>user_1<DT><DD>The first user-declared data field. </DD>
* <DT>user_2<DT><DD>The second user-declared data field. </DD>
* <DT>user_3<DT><DD>The third user-declared data field. </DD>
* <DT>user_4<DT><DD>The fourth user-declared data field. </DD>
* </DL>
* See the next section for a description of the addresses subsections.
*
* \par The fields of the addresses subsections
* The section for each entry contains a subsection \c addresses with
* in turn a subsection for each address. The addresses are enumerated
* in the order they are inserted, their keys are the numbers of
* inserting converted to a string. <BR>
* The keys defined in an address subsection are: <DL>
* <DT>headline</DT><DD> A headline shown for the address. </DD>
* <DT>position</DT><DD> The position of the person. </DD>
* <DT>org</DT><DD> The organization. </DD>
* <DT>orgunit</DT><DD> The organizational unit. </DD>
* <DT>orgsubunit</DT><DD> The organizational subunit. </DD>
* <DT>role</DT><DD> The role of the person. </DD>
* <DT>deliverylabel</DT><DD> A label for delivering to this address. </DD>
* <DT>address</DT><DD> The street, house no., flat etc line. </DD>
* <DT>zip</DT><DD> A zip or postal code. </DD>
* <DT>town</DT><DD> The town the person lives in in this address. </DD>
* <DT>country</DT><DD> The country for federal states. </DD>
* <DT>state</DT><DD> The state for federal states. </DD>
* </DL>
*
* \par The local configuration section
* For each kab II database file there are some settings that apply
* only to the file itselfes, not to all kab databases the user works
* with. These settings are called the local configuration. The settings
* are stored in the \c config section of the local file. The following
* keys are declared in this section: <DL>
* <DT>user_1</DT><DD>The \e name of the first user-declared field. </DD>
* <DT>user_2</DT><DD>The \e name of the second user-declared field. </DD>
* <DT>user_3</DT><DD>The \e name of the third user-declared field. </DD>
* <DT>user_4</DT><DD>The \e name of the fourth user-declared field. </DD>
* </DL>
* More fields will surely follow.
