== Chunks
This is sometime I keep looking up nice ways for. This in is from [https://stackoverflow.com/questions/312443/how-do-you-split-a-list-into-evenly-sized-chunks stackoverflow].
{{{c

def chunks(lst, n):
    """Yield successive n-sized chunks from lst."""
    for i in range(0, len(lst), n):
        yield lst[i:i + n]
}}}
== Get lines of file
{{{c
# as this stands, this removes all \r characters
# to convert from windows line endings to unix
# removes any trailing blank lines, then splits into lines
def flines(filename):
  return open(filename).read().replace("\r","").rstrip("\n").split("\n")
