                Sorts pics from a particular album into weekly albums relative
                to a target date based on the image date.

                The script will sort every media item from `SOURCE_ALBUM` album
                into child albums of the TARGET_FOLDER by calculating how many
                weeks after `TARGET_DATE` it was taken.

                The resulting folder structure will be:

                ```
                TARGET_FOLDER
                    ZERO_ALBUM
                    WEEKLY_PREFIX 1
                    WEEKLY_PREFIX 2
                    WEEKLY_PREFIX 3
                    ...
                ```
parameters:
    TARGET_DATE:    "Set to the target date."
    SOURCE_ALBUM:   "Set to the album with the unsorted pics. If it is a subfolder use a path like string."
    TARGET_FOLDER:  "Set to the target folder for the weekly albums. This folder will be the parent of the weekly albums."
    ZERO_ALBUM:     "Set to the album for pictures without a date or with a date before the target date."
    WEEKLY_PREFIX:  "Set to a prefix for the weekly albums."
    DISPLAY_DIALOG: "Set to true to display a summary dialog after everything is sorted."
compile:        false
