*
* Revision History:
Proposed (some changes for this present but not functional yet):
* 10-Apr-2004: EvoLoopS - Evolving SDSR Loop Simulator idea stolen
* from Hiroki Sayama <sayama AT is.s.u-tokyo.ac.jp>.
* -evolve option
* 09-Apr-2004: LoopS - Structurally Dissolvable Self-Reproducing Loop
* Simulator idea stolen from Hiroki Sayama
* <sayama AT is.s.u-tokyo.ac.jp>.
* -sheath and -dissolve options
* 12-Mar-2004: Added wrap-
ping.
* 15-Mar-2001: Added some flaws, random blue wall spots, to liven it up.
* This mod seems to expose a bug where hexagons are erased
* for no apparent reason.
* 01-Nov-2000: Allocation checks
* 16-Jun-2000: Fully coded the hexagonal rules. (Rules that end up in
* state zero were not bothered with since a calloc was used
* to set non-explicit rules to zero. This allows the
* compile-time option RAND_RULES to work here (at least to
* generation 540).)
* Also added compile-time option DELAYDEBUGLOOP for debugging
* life form. This also turns off the random initial direction
* of the loop. Set DELAYDEBUGLOOP to be 10 and use with
* something like this:
* xlock -mode loop -neighbors 6 -size 5 -delay 1 -count 540 -nolock
* 18-Oct-1998: Started creating a hexagon version.
* It proved not that difficult because I used Langton's Loop
* as a guide, hexagons have more neighbors so there is more
* freedom to program, and the loop will has six sides to
* store its genes (data).
* (Soon after this a triangular version with neighbors = 6
* was attempted but was unsuccessful).
* 10-May-1997: Compatible with xscreensaver
* 15-Nov-1995: Coded from Chris Langton's Self-Reproduction in Cellular
* Automata Physica 10D 135-144 1984, also used wire.c as a
* guide.

/*-
* From Steven Levy's Artificial Life
* Chris Langton's cellular automata "loops" reproduce in the spirit of life.
* Beginning from a single organism, the loops from a colony. As the loops
* on the outer fringes reproduce, the inner loops -- blocked by their
* daughters -- can no longer produce offspring. These dead progenitors
* provide a base for future generations' expansion, much like the formation
* of a coral reef. This self-organizing behavior emerges spontaneously,
* from the bottom up -- a key characteristic of artificial life.
*/
/*-
Don't Panic -- When the artificial life tries to leave its petri
dish (ie. the screen) it will (usually) die...
The loops are short of "real" life because a general purpose Turing
machine is not contained in the loop. This is a simplification of
von Neumann and Codd's self-producing Turing machine.
The data spinning around could be viewed as both its DNA and its internal
clock. The program can be initalized to have the loop spin both ways...
but only one way around will work for a given rule. An open question (at
least to me): Is handedness a requirement for (artificial) life? Here
there is handedness at both the initial condition and the transition rule.
