Data-sub path setting is set in featuresObject

[garethjns]

The main data path is set in params.paths.dataDir in predict.m and train.m but the subpath finding is hard coded in featuresObject (in both genFileListSomeSingles and genFileListNoConcat methods) to expect the paths from the competition data ie.

sDir = [paths.dataDir, str, '_', subs{s}, 'New'];
Or
sDir = [paths.dataDir, str, '', subs{s}, ''];

This path needs to be manually changed if folder names are different or if the code is run on OS using '/'. It should be migrated to top level scripts.
