-- Fix 2 issues with loading Rob Luke's BIDS datasets (#121)

* v1.35.2

-- Fix not finding .snirf files in Rob Luke's dataset   https://github.com/rob-luke/BIDS-NIRS-Tapping  because the file name pattern does not match any of the available options in DataFilesClass. Updated list of BIDS file name patterns to earch for.
-- Fix some bugs in DataFilesClass file search (change name of isempty method to IsEmpty so that there's no overriding of matlab's built in isempty: this caused DataFilesClass object to be mysteriously empty when executing constructor, also AddParentDirs method assigning incorrect name to FileClass member objects)

* -- Fix some bugs in unit test logging - and displaying call stack in case of error

* v1.35.3

-- Fix Rob Luke's https://github.com/rob-luke/BIDS-NIRS-Tapping dataset not being loaded correctly probe lacks sourcePos2D and detectorPos2D. It has sourcePos3D and detectorPos3D so we project 3D to 2D if the 2D fields are empty. If landmarks are missing then we use crude default 3D-to-2D projection algorithm. If landmarks are available then we use another algorithm that Sreekanth Kura and David Boas are developing

* -- Change syncSubmodules to not use version numbers any more and rely on dates instead
