class Object
# Returns true if this object is included in the argument(s). Argument must be
# any object which responds to +#include?+ or optionally, multiple arguments can be passed in. Usage:
#
# characters = ["Konata", "Kagami", "Tsukasa"]
# "Konata".in?(characters) # => true
#
# character = "Konata"
# character.in?("Konata", "Kagami", "Tsukasa") # => true
#
# This will throw an ArgumentError if a single argument is passed in and it doesn't respond
# to +#include?+.
