Detailed Description
Function Documentation
   int LIBMTP_Create_New_Album (LIBMTP_mtpdevice_t *device, LIBMTP_album_t *constmetadata)
       This routine creates a new album based on the metadata supplied. If the tracks field of the metadata contains a track listing, these tracks
       will be added to the album.

       Parameters:
	   device a pointer to the device to create the new album on.
	   metadata the metadata for the new album. If the function exits with success, the album_id field of this struct will contain the new ID
	   of the album.

	   o metadata->parent_id should be set to the parent (e.g. folder) to store this track in. Since some devices are a bit picky about where
	     files are placed, a default folder will be chosen if libmtp has detected one for the current filetype and this parameter is set to 0.
	     If this is 0 and no default folder can be found, the file will be stored in the root folder.
	   o metadata->storage_id should be set to the desired storage (e.g. memory card or whatever your device presents) to store this track in.
	     Setting this to 0 will store the track on the primary storage.
       Returns:
	   0 on success, any other value means failure.

   void LIBMTP_destroy_album_t (LIBMTP_album_t *album)
       This recursively deletes the memory for an album structure
       Parameters:
	   album structure to destroy

   LIBMTP_album_t* LIBMTP_Get_Album (LIBMTP_mtpdevice_t *device, uint32_t constalbid)
       This function retrieves an individual album from the device.
       Parameters:
	   device a pointer to the device to get the album from.
	   albid the unique ID of the album to retrieve.
       Returns:
	   a valid album metadata or NULL on failure.

   LIBMTP_album_t* LIBMTP_Get_Album_List (LIBMTP_mtpdevice_t *device)
       This function returns a list of the albums available on the device.
       Parameters:
	   device a pointer to the device to get the album listing from.
       Returns:
	   an album list on success, else NULL. If there are no albums on the device, NULL will be returned as well.

   LIBMTP_album_t* LIBMTP_Get_Album_List_For_Storage (LIBMTP_mtpdevice_t *device, uint32_t conststorage_id)
       This function returns a list of the albums available on the device. You can filter on the storage ID.
       Parameters:
	   device a pointer to the device to get the album listing from.
	   storage_id ID of device storage (if null, all storages)
       Returns:
	   an album list on success, else NULL. If there are no albums on the device, NULL will be returned as well.

       Referenced by LIBMTP_Get_Album_List().
   LIBMTP_album_t* LIBMTP_new_album_t (void)
       This creates a new album metadata structure and allocates memory for it. Notice that if you add strings to this structure they will be
       freed by the corresponding LIBMTP_destroy_album_t operation later, so be careful of using strdup() when assigning strings.
       Returns:
	   a pointer to the newly allocated metadata structure.

   int LIBMTP_Set_Album_Name (LIBMTP_mtpdevice_t *device, LIBMTP_album_t *album, const char *newname)
       This function renames a single album. This simply means that the PTP_OPC_ObjectFileName property is updated, if this is supported by the
       device. The album filename should nominally end with an extension like '.alb'.
       NOTE: if you want to change the metadata the device display about a playlist you must not use this function, use LIBMTP_Update_Album()
       instead!
       Parameters:
	   device a pointer to the device that contains the file.
	   album the album metadata of the album to rename. On success, the name member is updated. Be aware, that this name can be different than
	   newname depending of device restrictions.
	   newname the new name for this object.
       Returns:
	   0 on success, any other value means failure.

   int LIBMTP_Update_Album (LIBMTP_mtpdevice_t *device, LIBMTP_album_t const *constmetadata)
       This routine updates an album based on the metadata supplied. If the tracks field of the metadata contains a track listing, these tracks
       will be added to the album in place of those already present, i.e. the previous track listing will be deleted.
       Parameters:
	   device a pointer to the device to create the new album on.
	   metadata the metadata for the album to be updated. notice that the field album_id must contain the apropriate album ID.
       Returns:
	   0 on success, any other value means failure.
