Only use this if multiple setValues() are called for the same setPoints() The output weights and pointset must then be provided to the getValue function

Reimplemented from Gridder2D.

void TriangulatedGridder2D::setGridArea ( const Interval< float > &  , const Interval< float > &    )

virtual

Given that we want to calculate cpt, is data at dpt usable. Tells gridder that you will not call setGridPoint outside these ranges. May speed up calculation.
