/**

 *  New version of AknCommonDialogs class suporting dynamic drives such as

 *  remote drive. Use this instead of now deprecated old AknCommonDialogs.

 *

 *  A simple facade class that consists of static functions that launch UI

 *  components in a sequence. First, memory selection component is launched and

 *  then file/directory selection component. In save and move dialogs directory

 *  selection may not be shown if there are no subdirectories to choose from.

 *  In save dialog, finally filename prompt component is launched.

 *

 *  All methods have an obligatory resource ID parameter for memory selection

 *  because it contains the paths for both memories (Phone&MMC) (LOCATION

 *  structs). New TMemoryTypes functionality allows defining dynamic memories

 *  to be used.

 *

 *  If set, an observer is queried just before exiting the dialog.

 *  At this point the application can either reject or accept user's selection.

 *  Every dialog returns a boolean value which tells if user has selected

 *  something or not.

 *

 *  @lib CommonDialogs.lib

 *  @since S60 3.2

    /**

     * Bit flag definition of the memory types that will  be listed by the

     * dialog. These are used in the new functions to include for example

     * remote drives. In case new media types are added in the future, the

     * types can be added to the end of this enumeration.

     *

     * Application logic and UI specification is mainly interested in

     * division between 'phone memory' and 'MMC' with the latest addition of

     * 'remote drives'. In Symbian OS level this is somewhat more

     * complicated because these do not map directly to any drive or memory

     * type. For example try defining the drive letter for remote drive.

     *

     * Basically TMediaType could be used but the types may vary in the same

     * drive and application logic mostly understands only division between

     * 'phone' and 'MMC' memory - these do not map to TMediaType directly.

     * This the reasoning for this new enumeration.

     *

     * Uses binary flagging.

     *

     * Use for example 'EMemoryTypePhone|EMemoryTypeMMC|EMemoryTypeRemote' to

     * have phone memory, MMC and remote drives included.

     *

     * Notice: 0 value means no media included. Only

     * EMemoryTypePhone|EMemoryTypeMMC for legacy applications and

     * EMemoryTypePhone|EMemoryTypeMMC|EMemoryTypeRemote for new remote

     * drives-aware applications are supported for the time being.

     * Use EMemoryTypePhone|EMemoryTypeInternalMassStorage|EMemoryMMCExternal

     * |EMemoryTypeRemote for multiple drive support. And EMemoryTypeMMC will

     * be deprecated.
