/* ITERATION MACROS
TAG_ITER_DECLARECOUNTER must be used before using the iterators.
'level':
For each nested iteration, an additional TAG_ITER_DECLARECOUNTER
must be used with a different level number to avoid conflict with
the outer iterations.
Most cases don't have nested iterations and thus the level is just 0.
'tag':
Pretty much the elements' tag to iterate through.
