Iterate over the records in ascending sorted order.  Sorting occurs on the primary key value
starting at the specified startKey.
@param minKey the minimum primary key.
@param maxKey the maximum primary key.
@param startKey the initial iterator position.
@return record iterator
@throws IOException if an I/O error occurs.
@throws IllegalArgumentException if long keys are not in use or startKey 
is less than minKey or greater than maxKey.
