	Interpolate multiple field values at a particle position using CIC. More...

	Test whether a particle's vertical CIC stencil reads past the local fab. cic_interpolate reads cell-centered data at k0+1 and k0+2 with k0 in {pk-1, pk}, so the maximum read offset is pk+2. Returns true if the stencil is out of bounds and the caller should skip the particle. More...
