*
* FlavioRocchiTest
* You can find follows objects :
* - two interfaces (StoredBean & StoredValue).
* - two EntityBean which inherated StoreBean.
* - two Objects (Football & Weather) which inherated StoredValue.
* - a Comparer object which implemented Comparator.
* - main object called FlavioRocchiTest
*
* I could do the same software in a lot of different ways for example :
* I could store infomation regarding weather and football
* in two different xml files;reading & sorting them through DOM.
