/** \class FastMarchingExtensionImageFilterBase
* \brief Extend auxiliary variables smoothly using Fast Marching.
*
* Fast marching can be used to extend auxiliary variables smoothly
* from the zero level set. Starting from an initial position on the
* front, this class simultaneously calculate the signed distance and
* extend a set of auxiliary values.
*
* This class is templated over the level set image type, the auxiliary
* variable type and the number of auxiliary variables to extended. The initial
* front is specified by two containers: one containing the known points
* and one containing the trial points. The auxiliary variables on the front
* are represented by two auxiliary variable containers: one containing
* the value of the variables at the know points and on containing the
* value of the variables at the trail points.
*
* Implementation of this class is based on Chapter 11 of
* "Level Set Methods and Fast Marching Methods", J.A. Sethian,
* Cambridge Press, Second edition, 1999.
*
* For an alternative implementation, see itk::FastMarchingExtensionImageFilter.
