2141ba1e5cdForce deletion, `rm -f`, so `rm` doesn't complain about missingfiles.

8f75b07da23Lower the freespace threshold to 1B from 1GB. The higher threshold probablydid not have the desired effect, anyway: it only affects the size of free space regions that *persist* in the HDF5 file.

f6a85287986Initial commit of VFD SWMR demos: `credel` (cre)ates and (del)etes datasets andgroups. `gaussians` generates a couple of 2-D Gaussian curves that move at a constant speed inside of a rectangle and bounce off its sides. `gaussians` just displays. `wgaussians` records the "image" of the 2-D Gaussians to an extensible dataset. `rgaussians` reads the dataset and uses `curses(3)` to displays it as a "movie".
