* to be set through a vector of values using the
* SetParameters() method. This interface makes it easier to include
* parameterized image sources within ITK's
* optimization/registration framework.
*
* Concrete subclasses must impelement the methods SetParameters(),
* GetParameters() and GetNumberOfParameters().
