Fix path change issue when loading data into ARTwarp

[RohanK22]

It is a very simple fix that just saves the current path in a global variable before loading the data, and after the data is loaded it restores the current working directory back to the ARTwarp code directory.

Why don't you leave the path as it is, and use full file path names to load the data ? My memory is that it switches the working directory to the data folder, but if you used full file paths, that wouldn't be necessary.

I think the changes should load the ctr files by using their full path names instead of switching the current directory. I have removed the unnecessary cd(path) commands in the code.

Sorry for not getting to this earlier. this is the right approach, however Matlab has a nice 'fullfile' function which will join the bits of the path together, rather than using append like you have done: test=csvread(append(DATA(c1).folder, '/', DATA(c1).name)

Ok. I've changed it to use the 'fullfile' function instead.
