Verified with:
```py
myIterativeMean = iterativeMean()
print(myIterativeMean.mean)
myIterativeMean.addElement(2)
print(myIterativeMean.mean)
myIterativeMean.addElement(3)
print(myIterativeMean.mean)
```
Note that cannot simplify as follows in the general case of using images as
`element`s for instance:
```diff
diff --git a/datasets/raise/utils.py b/datasets/raise/utils.py
