SYNOPSIS

DESCRIPTION

       A range of metatiles for one or more maps, one or more zoom levels and an x/y range for a
       lon/lat bounding box.

       Is used to easily iterate over all those metatiles.

METHODS

   Tirex::Metatiles::Range->new(...)
       Create new range.

   $range->reset()
       Reset range, so that the next call to next() will return the first metatile in the range.

       Returns range itself.

   $range->count()
       Calculates how many metatiles there are in this range.

   $range->get_metatiles()
       Return the number of metatiles you already got out of this range with next().

   $range->to_s()
       Return string describing the range.

   $range->next()
       Get next metatile from the range.

       Returns undef if there are no more metatiles.
