Adding a Post-Condition to Task 1

The following code adds the post-condition to Task 1. The post-condition checks whether a geometry part exists in the Geometry > Parts manager node. If a part exists, the condition is satisfied.

Return to the Task01ImportGeometry class.
Locate the public Task01ImportGeometry() constructor.
Add the following code to this constructor:
```
// Makes sure that a geometry part is created.
setPostconditions(Collections.singleton(InternalFlowConditions.createPartCondition()));
```
where:
- setPostconditions() sets the post-condition for the task.
- Collections.singleton(InternalFlowConditions.createPartCondition()) is the condition that checks for a geometry part.
Add the missing import.
