Every abstract class should implement a static int StaticClassId() method

[orlandini]

Should you find the following error:
error: StaticClassId is not a member of TPZExample
chances are that TPZExample is an abstract class. If that is the case, follow these steps:

1. Create a static int TPZExample::StaticClassId()method.

2. Move the implementation of virtual int TPZExample::ClassId() to the recently created method.

3. Change the implementation of virtual int TPZExample::ClassId() to:

    int TPZExample::ClassId(){
        return TPZExample::StaticClassId();
    }
   

Have a nice day!
