* \class FunctionBase
* \brief Base class for all ITK function objects
*
* FunctionBase is the base class for ITK function objects. Specifically,
* the abstract method Evaluate() maps a point from the input space to a point
* in the output space.
*
* Subclasses must override Evaluate().
*
* This class is template over the input (domain) type and
* the output (range) type.
