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)
