/**
* \class MeshFunctionBase
* \ingroup QEMeshModifierFunctions
* \brief Base class for mesh function object modifiers.
*
* MeshFunctionBase is the base class for itkQE function objects specialised
* in Mesh "small" (reduced in range) modification.
* Subclasses of itk::FunctionBase cannot modify their InputType since
* the signature of their Evaluate( const InputType& ) method guarantees it.
* Consider a method that modifies (the geometry, the connectivity or both)
* a mesh.
* For large modifications of this mesh we follow the classical itk Filter
* schema, which implies duplicating the mesh which can be space consuming.
* But for small modifications (think of the Euler operators) that an
* algorithm needs to apply many times, this systematic duplication can
* be daunting.
* MeshFunctionBase thus offers a leightweight alternative to itk Filter.
* Subclasses of MeshFunctionBase, which should override Evaluate(), are
* function objects that apply reduced and localised modifications
* (geometry, or connectivity) on the InputType mesh.
*
* This class is template over the mesh type (to be modified) and
* the output (usually a created/deleted vertex or face) type.
*
