precizare :
1. Daca vreti sa faceti a = b + c, in loc de a += b , trebuie in loc de void operator += ( ... )
sa faceti Mare operator + ( ... ) , si sa returnati un vector Mare ( exemplu prima functie, Mare operator + ( Mare& ) )
2. Pentru comparari, se poate face usor > si >=, doar schimband returnurile ( fals cu adevarat, si invers ), dar
e de preferabil ca a > b sa se faca ca si b < a ( pentru a nu mai fi nevoie de introducerea unei noi comparari )
