This is a simple project that allow us to make practice all knowledge we already get in Observer Design Pattern

Our use case here is an Account System.

The subject we have to observe (Caisse.ts) is the set of balance and transactions. The user can add a transaction using a form. Each time he clicks on add button, he will see synchronously informations in observers components.

For the observers, we've there three : ListTrans.ts, NbTrans.ts, Solde.ts and Info.ts
