We should replace all plain pointers with smart pointers, either from std or from boost.

Some random notes

• Each class T for which a shared pointer std::shared_ptr<T> is used should feature a typedef std::shared_ptr<T> SP. This reduces the amount of code we have to write.
• Cyclic references have to be avoided using weak pointers.

ToDos

• ElementBase * -> std::shared_ptr<ElementBase>
• return type of Object::clone
• (almost) all occurrences of the keyword new
• replace (occurrences of) Pointer class
• replace pointers in Classic/Fields with smart pointers (#744 (closed))
• replace plain pointers in Classic/AbsBeamline with smart pointers (#746)
