315	psMetadataIteratorSet	robert.desonia@…	eugene	"Iterating using regex seems a bit awkward, as there is no good way to set the 
iterator at the first match of regex.  If you use psMetadataIteratorSet(md,0), 
you can set the iterator to the first on the list, but you need to know if that 
matches the regular expression, and if not, call psMetadataGetAndIncrement to 
search for the first matching occurrance. 
 
I think that psMetadataIteratorSet should take a regex parameter just like 
psMetadataGetAndIncrement.  PS_LIST_HEAD would position to the first matching 
regex, PS_LIST_TAIL would position to the last matching regex, and n>0 would 
position to the (n-1)th matching occurrance. 
 
In other words, regex would be used to virtually subset the list and one could 
consider oneself iterating over that subset. 
 
psMetadataIteratorSet(psListIterator* iter, int location, const char* regex);
