/**
* @class vtkArrayInterpolate
*
* Computes the weighted sum of a collection of slices from a source
* array, and stores the results in a slice of a target array. Note that
* the number of source slices and weights must match, and the extents of
* each source slice must match the extents of the target slice.
*
* Note: The implementation assumes that operator*(T, double) is defined,
* and that there is an implicit conversion from its result back to T.
*
* If you need to interpolate arrays of T other than double, you will
* likely want to create your own specialization of this function.
*
* The implementation should produce correct results for dense and sparse
* arrays, but may perform poorly on sparse.
*
* @par Thanks:
* Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National
* Laboratories.
