        * Two-phased constructor. Leaves on failure.

        * This function shall be used to create the access point 

        * settings/selection handling UI object. It is customizable through 

        * the parameters. This object is a small layer above the UI part and

        * it provides a standard interface to select, edit, create access 

        * points. It has two main parts, Select and Edit. The first parameter,

        * aStartWithSelection gives whether we would like to select or edit.

        * In case of selection, there is the possibility to use this module in

        * many applications. For this, two layouts are implemented, 

        * one is list pane used by General Settings which provides the list in

        * a list-pane. The other layout is for the other applications 

        * requiring access point selection, a popup-list style as the decision

        * I know about was that General Settings will use list-pane and all

        * other apps. popup-list style. It is the caller who selects the style

        * so if spec. says otherwise, this module still can be used.

        * It is also possible to start the UI without selection, so if any 

        * module has a 'linked/default/etc.' access point and stored it's UID,

        * the module can simply call the editor part of the UI without having

        * to select the AP once more. In case of editing only, 

        * (aStartWithSelection is EFalse), all other construction parameters 

        * are ignored and after construction caller can simply call 

        * DoRunSettingsL(..). In case of selection, a lot of other parameters 

        * can be specified to fulfil all requirements. There are three types 

        * of Options menu available: 

        * EApSettingsSelMenuNormal, 

        * EApSettingsSelMenuSelectOnly,

        * EApSettingsSelMenuSelectNormal.

        * <br>

        *-EApSettingsSelMenuSelectOnly: Only Select is visible, 

        *                               no way to edit, delete, create, etc.

        * <br>

        * -EApSettingsSelMenuNormal:    Options menu specified in General 

        *                               Settings, contains Edit, Delete, 

        *                               Create new, etc. menu items.

        * <br>

        * -EApSettingsSelMenuSelectNormal: Same as in EApSettingsSelMenuNormal

        *                                BUT the first item is Select. 

        *                                This one makes it possible to select 

        *                                an access point and also possible to 

        *                                edit, create, delete, etc.

        * <br>

        * The following three parameters specify the filtering and ordering 

        * criteria for the selection list creation. First, it is possible to

        * specify which ISP-type we are looking for. The possible values are:

        * <br>

        * KEApIspTypeInternetOnly:  Filter allows only access points that are

        *                           capable of only internet access.

        * <br>

        * KEApIspTypeWAPOnly:       Filter allows only access points that are 

        *                           capable of only WAP access.

        * <br>

        * KEApIspTypeInternetAndWAP: Filter allows only access points that are

        *                           capable of internet AND WAP access.

        * <br>

        * KEApIspTypeWAPMandatory:  Filter allows only access points that are

        *                           capable of WAP access AND contain 

        *                           mandatory WAP settings.

        * <br>

        * KEApIspTypeAll:           No filtering is done for the isp-type,

        *                           all types of access points are shown.

        * <br>

        * It is possible to combine them by simply adding/or-ing together 

        * the values, filtering will be done in such a way that only access 

        * points with the listed ISP-types will be shown. Second filtering

        * possibility (aBearerFilter) is the desired bearer type. The possible

        * values are the values of the TApBearerType enum type and their 

        * combinations, as in case of the ISP type. The ordering of the list

        * can be specified with the aSortType parameter. It can have the

        * following values:

        * KEApSortUidAscending:     The sorting is done according to the ID 

        *                           of the access points in ascending order.

        * KEApSortUidDescending:    The sorting is done according to the ID 

        *                           of the access points in descending order.

        * KEApSortNameAscending:    The sorting is done according to the name

        *                           of the access points in ascending order.

        * KEApSortNameDescending:   The sorting is done according to the name

        *                           of the access points in descending order.

        * Caution! The ordering values can not be combined!

        * @param aStartWithSelection    A boolean value indicating whether to 

        *                               select or edit an ap.

        * Two-phased constructor. Leaves on failure.

        * This function shall be used to create the access point

        * the parameters. This object is a small layer above the UI part and

        * it provides a standard interface to select, edit, create access 

        * points. It has two main parts, Select and Edit. The first parameter,

        * aStartWithSelection gives whether we would like to select or edit.

        * In case of selection, there is the possibility to use this module in

        * many applications. For this, two layouts are implemented, one is list

        * pane used by General Settings which provides the list in a list-pane.

        * The other layout is for the other applications requiring access point

        * selection, a popup-list style as the decision was that General 

        * Settings will use list-pane and all other apps. popup-list style. 

        * It is the caller who selects the style so if spec. says otherwise,

        * this module still can be used. It is also possible to start the UI 

        * without selection, so if any module has a 'linked/default/etc.'

        * access point and stored it's UID, the module can simply call the 

        * editor part of the UI without having to select the AP once more.

        * In case of editing only, (aStartWithSelection is EFalse), all other 

        * construction parameters are ignored and after construction caller can

        * simply call DoRunSettingsL(..). In case of selection, a lot of other

        * parameters can be specified to fulfil all requirements. There are 

        * three types of Options menu available: EApSettingsSelMenuNormal, 

        * EApSettingsSelMenuSelectOnly, EApSettingsSelMenuSelectNormal.

        * <br>

        *-EApSettingsSelMenuSelectOnly: Only Select is visible, no way to edit,

        * <br>

        * -EApSettingsSelMenuNormal:Options menu specified in General Settings,

        * <br>

        * -EApSettingsSelMenuSelectNormal: Same as in EApSettingsSelMenuNormal 

        *   BUT the first item is Select. This one makes it possible to select

        *   an access point and also possible to edit, create, delete, etc.

        * <br>

        * The following three parameters specify the filtering and ordering

        * criteria for the selection list creation. First, it is possible to 

        * specify which ISP-type we are looking for. The possible values are:

        * <br>

        * KEApIspTypeInternetOnly: Filter allows only access points that are 

        *   capable of only internet access.

        * <br>

        * KEApIspTypeWAPOnly: Filter allows only access points that are 

        *   capable of only WAP access.

        * <br>

        * KEApIspTypeInternetAndWAP: Filter allows only access points that are 

        *   capable of internet AND WAP access.

        * <br>

        * KEApIspTypeWAPMandatory: Filter allows only access points that are 

        *   capable of WAP access AND contain mandatory WAP settings.

        * <br>

        * KEApIspTypeAll: No filtering is done for the isp-type, all types of

        *   access points are shown.

        * <br>

        * It is possible to combine them by simply adding/or-ing together the

        * values, filtering will be done in such a way that only access points

        * with the listed ISP-types will be shown. Second filtering possibility

        * (aBearerFilter) is the desired bearer type. The possible values are 

        * the values of the TApBearerType enum type and their combinations, as

        * in case of the ISP type. The ordering of the list can be specified 

        * with the aSortType parameter. It can have the following values:

        * KEApSortUidAscending: The sorting is done according to the ID of 

        *   the access points in ascending order.

        * KEApSortUidDescending: The sorting is done according to the ID of 

        *   the access points in descending order.

        * KEApSortNameAscending: The sorting is done according to the name of

        *   the access points in ascending order.

        * KEApSortNameDescending: The sorting is done according to the name of

        *   the access points in descending order.
