+To test:
+We need to test add_annotation, add_shape, add_layout_image
+
+The possible entries for row and col are:
+
+code, type
+ia: (int,'all')
+lea: (list,'all')
+a: 'all'
+i: int
+le: list, len equals other list len
+lu: list, len unequal
+
+# Rather than test this huge space of function inputs, let's break it down:
+
+Test if (int,'all') (list,'all') ('all',int) ('all',list) set an "all" flag (also test that not this doesn't set the all flag e.g., int, list (int,'notall'),etc.)
+
+Test the combinations formed by taking the cartesian product {a,i,l}x{a,i,l} and just see if they give the predicted index pairs.
+
+Test to see if the part of the code that iterates through the plots works, e.g., check that empty list does nothing and list of (row,col) pairs does work.
+
+Check to see that range is converted to list when passed in these forms (range,'all') range etc.
