% newStr=ReplaceLineTerminators(str, newTerminator)
%
% Replace either mac, windows, or linux style line terminators in the
% string "str" with the the specified line terminator and return the
% result. Strings containing Macintosh, Windows or Unix line terminators
% (see below), or any mix thereof are handled as input.
%
% The argument "newTerminator" may be either the terminator characters
% which you want to substitute in or else a string identifying a
% platform. If you provide terminators, these must be a combination of [
% \f\n\r\t\v], while terminators for the desired platform can be specified
% by the identifiers in teh middle column below:
%
% Macintosh: 'Mac', 'Macintosh', 'OS 9' 'OS9' CR 13
% Windows: 'Win', 'Windows', 'DOS', 'MSDOS' CRLF 13 10
% Unix: 'Unix','Linux', 'BSD', 'OS X', 'OSX' LF 10
