Add value composition to for_each

[jipclaassens]

unit<uint8> Continents := Classifications/Continents
, storagename = "= propvalue(store_Continents, 'storagename')", storagereadonly = "True"
{
    attribute<LatLong>  geometry       (poly);
    attribute<string>   name                  := Classifications/Continents/name;
    attribute<.>        per_grid     (domain) := poly2grid(geometry , domain);
    attribute<World>    World_rel             := const(0[WOrld],.);

    container V := for_each_nedv(AsItemName(name), String(ID(.))+'[..]', void, .);

    container perContinent := 
        for_each_nedv(
            name
            , 'geometry[V/'+name+']'
            , void
            , LatLong
        );
}
