Return the next line of the file as a string.
FGETL(FID) returns the next line of a file associated with file
identifier fid as a MATLAB string. The newline and a carriage return
if it preceeds it are NOT included. Use FGETS () to get the next line
with those characters INCLUDED. If just an end-of-file is encountered
then -1 is returned.
IMPORTANT: Please note that this is intended to be used ONLY with
text files. If by mistake you read a "binary" file
without newline characters this routine may take a
long time for large files.
Example: (equivalent to 'type fgetl.m')
line = fgetl(fid);
if ~isstr(line), break, end
