USAGE:
% Reads the first line (default)
s = readline('data.txt');
% Reads the 8th line
s = readline('data.txt',8);

% Reads the [1 2 4 8] lines
s = readline('data.txt',[1 2 4 8]);
% Reads last 7 lines
s = readline('data.txt',[-7; -1]);
% Or just, reads the whole file
s = readline('data.txt','all');

NOTES:
In general, the output is a cell of strings. You may force a string matrix output with a third argument
s = readline('data.txt','all','string');

4.0.0.0

V4.0 Now accepts 'all' input. Uses TEXTSCAN instead of TEXTREAD.
1.1.0.0

V3.0 Rewritten code. Negative NLINES values now indicated number of line from the End-of-File, instead of from the last line. New pairwise optional inputs for TEXTSCAN.
1.0.0.0

1. I change the loops of FGETL by a single TEXTREAD function as suggested by Urs (us) Schwarz.

2. New easy way for the lines inputs. Now accepts ascending and descending (negative) ranges.

3. I eliminate the file identifier input.
