@Override
	public Iterator<AddressRange> iterator() {
		return this;
	}
Constructs an AddressRangeIterator over all ranges between the given start address and the
given end address that have a defined value. If start is in the middle of a defined range,
the first range returned will truncated to start with the given start address. 
If the endAddress is in the middle of a defined range, the last range will be truncated to
end with the given end address
@param rangeMap the AddressRangeMapDB to iterate over
@param start the address where the iterator should start
@param end the address where the iterator should end
@throws IOException if a database I/O exception occurs
