So far, implements a more efficient sum_to kernel that will have a maximum write contention of the number of blocks (groups of 1024 threads) running concurrently. Operations within each block scale with
log2(min(chunk_size, block_size)). Resolves #332, and will depend on #380 for @ViliamVadocz 's fix to atomicMaxf and atomicMinf.
