AMREX_GPU_HOST_DEVICE AMREX_INLINE void	ablastr::particles::compute_weights (const amrex::ParticleReal xp, const amrex::ParticleReal yp, const amrex::ParticleReal zp, amrex::GpuArray< amrex::Real, 3 > const &plo, amrex::GpuArray< amrex::Real, 3 > const &dxi, int &i, int &j, int &k, amrex::Real W[3][2]) noexcept
	Compute weight of each surrounding node (or cell-centered nodes) in interpolating a nodal ((or a cell-centered node) field to the given coordinates. If template parameter IdxType is amrex::IndexType::CellIndex::NODE, then the calculations will be done with respect to the nodes. If template parameter IdxType is amrex::IndexType::CellIndex::CELL, then the calculations will be done with respect to the cell-centered nodal. This currently only does linear order.

	Interpolate nodal field value based on surrounding indices and weights.

	Scalar field gather for a single particle. The field has to be defined at the cell nodes (see https://amrex-codes.github.io/amrex/docs_html/Basics.html#id2).
