# These functions take a bunch of source data in some format and turn
# it into nicely labeled fields that we know how to initialize a card from.
# Both return a dict that maps field names to lists of possible values,
# paired with the index that we read that particular field value from.
# So, {fieldname : [(idx, value), (idx, value)...].
# Usually we want these lists to be length 1, but you never know.

# Of course to make things nice and simple, that dict is the third element
# of a triple that reports parsing success and valid success as its 
# first two elements.

# This whole things assumes the json format of mtgjson.com.

# Here's a brief list of relevant fields:
# name - string
# names - list (used for split, flip, and double-faced)
# manaCost - string
# cmc - number
# colors - list
# type - string (the whole big long damn thing)
# supertypes - list
# types - list
# subtypes - list
# text - string
# power - string
# toughness - string
# loyalty - number

# And some less useful ones, in case they're wanted for something:
# layout - string
# rarity - string
# flavor - string
# artist - string
# number - string
# multiverseid - number
# variations - list
# imageName - string
# watermark - string
# border - string
# timeshifted - boolean
# hand - number
# life - number
# reserved - boolean
# releaseDate - string
# starter - boolean
