Question: TestDome - Safe
Solution by Arash Partow 2014

The Safe class is used as a simulation for a bank safe. It needs to
satisfy the following conditions:

The getItems() property should return the content of the safe.

The addItem(item) method should add a new item to the safe. If the
safe is full, std::logic_error should be thrown.

The getDescription() method should return the safe's description.
If the safe is full, it should return "Safe is full"; otherwise, it
should return a message in the format "Safe: numOfItems/capacity".
For example, if the capacity of the safe is two and one item is
added, it should return: "Safe: 1/2".

Fix the bugs!
