dez 1.0

I packaged up the best version of the delta generator into dez-1.0. It and some details are available on the dez home page.

A couple of nights ago I tried one of the hashtable ideas from a previous post. It made a big improvement so I kept whittling it away until there really wasn't much of a hash table left apart from a couple of arrays. Fastest version using the least memory. Open addressing just didn't handle some bad cases at all well.

I didn't see the point in keeping the others around so i only kept this one in the release.

And that should be me done with this for a while.
