Method Stdio.FILE()->line_iterator()

Method line_iterator: object line_iterator(int|void trim)
Description: Returns an iterator that will loop over the lines in this file. If trim is true, all '\r' characters will be removed from the input.
Note: It's not supported to call this method more than once unless a call to seek is done in advance. Also note that it's not possible to intermingle calls to read , gets or other functions that read data with the line iterator, it will produce unexpected results since the internal buffer in the iterator will not contain sequential file-data in those cases.
