fileparts2(file)

fileparts without missing trailing slash bug

% Purpose: Fixes mixing trailing slash bug in fileparts. If path is a dir without
% a trailing slash, will add the slash so fileparts gives expected pathstr.
%
% Usage: [pathstr, name, ext] = fileparts2(file)
%
% Explanation:
% Given a directory structure: ./parent/child/
%
% Problem:
% fileparts(parent/child/) = parent/child % Expected
% fileparts(parent/child) = parent % Bug
%
% Solution:
% fileparts2(parent/child/) = parent/child % Expected
% fileparts2(parent/child) = parent/child % Fixed bug
