function checkImageHandleArray(hImage,mfilename)
%checkImageHandleArray checks an array of image handles.
%   checkImageHandleArray(hImage,mfilename) validates that HIMAGE contains a
%   valid array of image handles. If HIMAGE is not a valid array,
%   then checkImageHandles issues an error for MFILENAME.
