balance
-------


 somehow map the get_entries pipe to entry and do the foreach loop, so the loop will work async
 balance = 0
 balance_struct (tree) ;
 for(entry in parse_entries(FILE* f, from = unix_epoch | -e, to = now)) {
	date = entry->date // useful for sorting?
	for (record in parse_records(entry)) {
		int get_rec_ptr = record->nn_name; // to get the string name and to verify with other records
		int get_val = record->amount;
		balance_struct.add(get_rec_ptr, get_val); // add value 'get_val' to 'get_rec_ptr'
		balance += get_val;
	}
 printf("-----------------\n");
 printf("%s %d", denom, balance);
}
