/** \class TransformParametersAdaptorBase
* \brief Base helper class intended for multi-resolution image registration.
*
* During multi-resolution image registration, it is often useful to expand
* the number of parameters describing the transform when going from one level
* to the next. For example, in B-spline registration, one often wants to
* increase the mesh size (or, equivalently, the control point grid size) for
* increased flexibility in optimizing the transform. This requires the
* propagation of the current transform solution to the next level where the
* solution is identical but with an increase in the number of parameters.
* This base class and those derived classes are meant to handle these types of
* situations.
*
* Basic usage will involve the user specifying the required fixed parameters, i.e.
*
* \code
* transformAdaptor->SetTransform( transform );
* transformAdaptor->SetRequiredFixedParameters( fixedParameters );
* transformAdaptor->AdaptTransformParameters();
* \endcode
*
* which will adjust the transform based on the new fixed parameters.
