/**
* Flyweight (Character)
* declares an interface through which flyweights can
* receive and act on extrinsic state.
*
* ConcreteFlyweight (CharacterA, CharacterB, ..., CharacterZ)
* implements the Flyweight interface and adds storage
* for intrinsic state, if any. A ConcreteFlyweight object
* must be sharable. Any state it stores must be intrinsic,
* that is, it must be independent of the
* ConcreteFlyweight object's context.
*
* UnsharedConcreteFlyweight (not used in program)
* not all Flyweight subclasses need to be shared. The Flyweight
* interface enables sharing, but it doesn't enforce it. It is
* common for UnsharedConcreteFlyweight objects to have
* ConcreteFlyweight objects as children at some level in the
* flyweight object structure (as the Row and Column classes have).
*
* FlyweightFactory (CharacterFactory)
* creates and manages flyweight objects ensures that flyweight
* are shared properly. When a client requests a flyweight, the
* FlyweightFactory objects assets an existing instance or
* creates one, if none exists.
*
* Client (FlyweightApp - Main)
* maintains a reference to flyweight(s).
* computes or stores the extrinsic state of flyweight(s).
