Implement basic functionality for Transaction.py

[ngiachou]

Main task

Tansaction.py should contain a single class Transaction which encapsulates basic functionality of a single transaction.

It should contain the following properties:

• product_list: list(Product)
• environment_characteristic: string
• place: string this is practically a bool (in or out) or it could be implemented as an enum.
• date: datetime.date

__init__() should be implemented. __repr__() could be implemented. The representation should be a string of the following form: "(<date>, <environment_characteristic>, <place>, <product_list>)", where date could be any date (possibly not in the future), place depends on the implementation and a list of products (possibly should be checked if the list is empty, since it doesn't make any sense to have an empty product list in a transaction).

Example: a possible string representation of a transaction could be the following:

• "('2018/09/30', 'friends', 'in', [('pizza', 10.00), ('juice', 2.45)])"
