/**
* @class vtkImplicitSum
* @brief implicit sum of other implicit functions
*
* vtkImplicitSum produces a linear combination of other implicit functions.
* The contribution of each function is weighted by a scalar coefficient.
* The NormalizeByWeight option normalizes the output so that the
* scalar weights add up to 1. Note that this function gives accurate
* sums and gradients only if the input functions are linear.
