      The beginnings of a toy version of assign written in Comet. I'm · ef81939b

      working on getting a feeling of whether or not it's feasible to
      implement assign in Comet. I think if it is, it would be a huge win in
      terms of maintainability and extensibility.
      So far, it's looking very promising. I'm struggling a bit with the
      syntax, and the lack of an API reference. But, once I figure out how
      to do what I need, it's making a lot of sense.
      All this program does so far is try to respect the number of slots on
      physical nodes - ie. not assign more than one vnode to a pnode, but it
      can do arbitrary numbers instead of just 1.
      It does not read top/ptop files, doesn't know about types, doesn't try
      to minimize any score, doesn't do features/desires, doesn't know about
      links at all, etc. Like I said, it's the beginnings of a toy program.
      It looks to me like what we're going to end up doing is writing a
      program to produce Comet programs. One of the cool things about this
      is that it means we can leave out any constraints, etc. that are not
      relevant to the particular mapping problem at hand. And, it should
      make it easy for us to plug in other search techniques (ie. write the
      obvious ones for certain pathological cases, like snakes and
