#   to_asm()                    spit out asm (not including label)
# keys are intervals "500..555" of byte addresses for each script
# last byte is not inclusive(?) really? according to who??

class MapScriptHeader:
    """parses a script header

    This structure allows the game to have e.g. one-time only events on a map
    or first enter events or permanent changes to the map or permanent script
    calls.

    This header a combination of a trigger script section and a callback script
    section. I don't know if these 'trigger scripts' are the same as the others
    referenced in the map event header, so this might need to be renamed very
    soon. The scripts in MapEventHeader are called XYTrigger.

    trigger scripts:
    [[Number1 of pointers] Number1 * [2byte pointer to script][00][00]]

    callback scripts:
    [[Number2 of pointers] Number2 * [hook number][2byte pointer to script]]

    hook byte choices:
        01 - map data has already been loaded to ram, tileset and sprites still missing
            map change (3rd step)
            loading (2nd step)
            map connection (3rd step)
            after battle (1st step)
        02 - map data, tileset and sprites are all loaded
            map change (5th step)
        03 - neither map data not tilesets nor sprites are loaded
            map change (2nd step)
            loading (1st step)
            map connection (2nd step)
        04 - map data and tileset loaded, sprites still missing
            map change (4th step)
            loading (3rd step)
            sprite reload (1st step)
            map connection (4th step)
            after battle (2nd step)
        05 - neither map data not tilesets nor sprites are loaded
            map change (1st step)
            map connection (1st step)

    When certain events occur, the call backs will be called in this order (same info as above):
        map change:
            05, 03, 01, 04, 02
        loading:
            03, 01, 04
        sprite reload:
            04
        map connection:
            05, 03, 01, 04 note that #2 is not called (unlike "map change")
        after battle:
