Memory Recovery

Because in most languages objects are dynamically allocated, they must be recovered at run-time. There are two broad approches to this:

Force the programmer to explicitly say when a value is no longer being used:
```
		delete aCard; // C++ example
```
Use a garbage collection system that will automatically determine when values are no longer being used, and recover the memory.
