Week 6 - Editing Zest Complex Conditional

This is the sixth week: the exam session is about to finish.
This week I worked on the code I wrote last week following some comments and suggesions from the mentor.
Most important point were:

• Creation of a new class: ZestStructuredExpression;
• Modified inheritance of classes

the previous two points were to avoid code duplication for the ZestExpression[And,Or]. The current structure is the following:

• Developed the code of the method deepCopy for all the new classes.

Last week I didn't wrote this method.

• Made some structural changes (e.g. deleted the reference to the parent of a conditional, the name, ...).

Next week is reserved for tests and, maybe, I'll try to integrate it at the ZAP side.
