Clone recommended item builds

# A Python script to allow you to 'clone' a customized set of recommended items.
# Written by RheingoldRiver.  Feel free to modify and share it but please don't
# claim you wrote it yourself if you do so.

# This code is intended to work with Enigma's Recommended Items Changer.  I am
# in no way affiliated with Enigma and any errors here are entirely my own.
# If you have League installed in a different directory, edit the variables
# dirOrig and dirNew accordingly.

# The inputs are (1) a string of the champion whose build you want to clone;
# (2) a vector of strings of the champions to which you want to clone the build;
# (3) a string denoting which mode you want to take the build from; and (4)
# a string denoting which mode you want to copy the build to.  Mode strings are
# "sr" for Summoner's Rift"; "dom" for Dominion; "pg" for Proving Grounds ARAM;
# and "tt" for Twisted Treeline.

# Example inputs:
#    cloneBuild("Sona",["Janna","Nami","Lulu"],"sr","sr")
# will copy your Summoner's Rift Sona build to Janna, Nami, and Lulu on
# Summoner's Rift.
#    cloneBuild("Irelia",["Irelia"],"sr","dom")
# will copy your Summoner's Rift Irelia build to Irelia on Dominion.

# If one of your builds contains items not available on a particular map then
# the program will still work; those items will just not appear in your
# recommended items on that map.

# This code is not exhaustively tested, so make sure you create a backup
# before using it.
