#include <itkFEMP.h>
Pointer used to store polymorphic elements in STL arrays.
FEMP holds a pointer to objects of class T and its derived classes. it behaves like a special kind of pointer. Special pointers to object can be used to store polymorphic arrays in STL. The basic idea of the special pointer is: whatever you do to the pointer (object of class FEMP), is also reflected on the object within (pointed to by m_Data member). For example: if you copy the special pointer, an object within is also copied.
Class T should have a member Clone() which produces a copy of an object. This is important in polymorphic classes, where object of the derived class should be created when copying an existing object.
Class T should also include typedefs T::Pointer and T::ConstPointer that define standard pointers to the class. Note that these could be SmartPointer classes.

Asignment operator
Self assignments don't make sense.
First destroy the existing object on the left hand side
Then clone the one on the right hand side of the expression (if not NULL).
