loadGroupLogsUI shows a dialog to choose one or more .hebilog files 
 to load into memory.
 
    This method lets users choose one or more raw .hebilog
    files via a file selector dialog and loads them into memory. 
    The output is a cell array of the conversion result for each 
    selected file.
 
    The optional parameters are the same as LOADGROUPLOG.
 
    'View' Parameter (optional)
       'Simple'  loads only simple feedback. This is appropriate
                 for most users and results in much smaller log
                 files. (default)
       'Full'    loads all available feedback. This is appropriate
                 for advanced users that need additional timestamps
                 or data from less common sensors.
       'IO'      loads feedback fields specific to I/O devices,
                 such as analog and digital pins, or the button and
                 slider states of the HEBI Mobile I/O app.
       'Mobile'  loads feedback fields specific to mobile devices,
                 such as GPS and ARKit/ARCore estimates.
 
     Example:
        % Load selected files and plot position feedback
        hebiLogs = HebiUtils.loadGroupLogsUI();
        HebiUtils.plotLogs(hebiLogs, 'position');
 
     Example:
        % Load selected files as 'full' structs
        hebiLogs = HebiUtils.loadGroupLogsUI('View', 'full');
 
     Example:
        % Add info/gains if available
        [hebiLogs, infos, gains] = HebiUtils.loadGroupLogsUI();
