PURPOSE ^

SAVE_AVW_IMG(img,fname,vtype)

SYNOPSIS ^

function save_avw_img(img,fname,vtype);

DESCRIPTION ^

  SAVE_AVW_IMG(img,fname,vtype)

  Save an array (img) as an analyse file (only the .img) 
   for either a 2D or 3D or 4D array (automatically determined)
 
  vtype is a single character string: 'b' (unsigned) byte, 's' short, 
                                      'i' int, 'f' float, or 'd' double

  The filename (fname) must be a basename (no extensions)
