* The Sus
class represents a system under specification

* - a description declaring what kind of system it is
*
- an
ExampleLifeCycle
which defines behaviour before/after example and test
* It is also an ExampleLifeCycle
so it can refine the passed cycle
*
* In specifications, a Sus "should" or "can" provide some functionalities which are defined in Examples
* A Sus is "executed" during its construction and failures and errors are collected from its examples
