setup.m should adjust for pc vs mac/unix

[lpuettmann]

Hi Ben,

your setup.m script in Metrics/MATLAB/setup.m doesn't work well on Windows computers because of the different path delimiters / vs . I realized this when .git paths showed up on my Matlab path.

It's works for both if you replace

thisPathSplit = strread(thisPath,'%s','delimiter','/'); 

with

if ismac | isunix
    thisPathSplit = strread(thisPath,'%s','delimiter','/');
elseif ispc
    thisPathSplit = strread(thisPath,'%s','delimiter','\\');
end  

best, Lukas
