Title: TST: Test for selem.cube

Add test case for selem.cube

Also begs a minor question - for organizing test cases while tracking. Would it be better to write test cases/functions in same order as they are in module?
Like if the order of functions in selem.py is
```
selem.square()
selem.rectangle()
selem.disk()
```
should the test cases for each of these also be in same order? This is just a personal preference but can be ignored depending upon what others think..
