breed.py - a web application for finding breeding chains for pokemon moves.

You can add a parent into the list by appending ?parent=ID to the url
(where ID is the national ID number of a pokemon).
You can specify the Generation by adding ?gen=GEN to the url
(where GEN is 1, 2, 3, or 4).

The database is from Veekun, and you can get it at <http://git.veekun.com/>.


HOW BREEDING WORKS

When two pokemon are in the Daycare Center and both Pokemon share a breeding
group and the two pokemon are of opposite gender, they may make an egg.

If so, then the following rules hold:
 - The Species of the egg will be the Base form of the female parent.
    - If the mother is Nidoran♀, the baby will be Nidoran♀ or Nidoran♂
    - If the mother is Illumise, the baby will be Volbeat or Illumise.
 - For each of the moves known by the male parent, if the baby can learn the
   move as an Egg Move or by TM, the baby will know that move.
    - If the baby can learn a move by Level Up, and *both* parents know that
      move, then the baby will start out knowing that move.


Weirdness:

 - In some cases, there is an extra baby form which can only be created by
   giving the mother a special Incense. In these cases, the baby usually can
   learn some moves which the base form cannot.
 - Smeargle can learn *any* move via sketch
    + except Struggle (all Generations)
    + except Selfdestruct, Explosion, Metronome & Transform (Gen II)
    + except Chatter (Gen IV)
 - Male-only pokemon *can* pass on moves when they breed with ditto, but
   only to the base form of that species (because of ditto). The only
   Male-only pokemon which have any Egg Moves are Tyrogue, Nidoran♂ and
   Volbeat. Nidoran♂ and Volbeat don't count, because of the weirdness
   mentioned above.


TODO list:
 - Add a moveset chain generator.
 - Sort the move chain list. First group by breeding group, then sort by name
   (or something. Figure out some sort of rank for figuring out best pokemon to
   display a group under. (This mostly matters at the parent level; there's
   usually not much choice deeper in the chains.)
    Possible factors for parent pokemon: evolution stage, level move learned at,
        evolution method (level is better than trade w/ item).
    Possible factors for non-parent pokemon: i dunno. maybe the number of groups it's in.
 - Add Smeargle (Sketch)
 - Fix babies (for real)
