ICollectionFilter

```
public interface ICollectionFilter
```
A collection filter is used by the CrossSection class to filter elements of the source collection.
Imagine to have a list of agents of the class MyAgent, which contains a boolean variable isFemale and an int variable age.

In order to obtain the list of ages of the males in the collection, the user can crate a class inheriting from ICollectionFilter

During the cross section iteration of the list, the isFiltered method is passed the current object and the relative value is read only if the filter returns true.
