dm - The mesh, with coordinate maps defined either by a PetscDS for the coordinate DM (see DMGetCoordinateDM()) or implicitly by the coordinates of the corner vertices of the cell: as an affine map for simplicial elements, or as a multilinear map for tensor-product elements
cell - the cell whose map is used.
numPoints - the number of points to locate + refCoords - (numPoints x dimension) array of reference coordinates (see DMGetDimension())
realCoords - (numPoints x coordinate dimension) array of coordinates (see DMGetCoordinateDim())
