"""Splay tree
Logan Ingalls <log@plutor.org>
Sept 3, 2012

Note that I only implemented insert and find. Delete is trivial,
and isn't the interesting part of splay trees. Some of these
algorithms would be simpler, but I chose to do this without parent
links from the tree nodes.

Example output on my desktop computer:

import time

def RateLimited(maxPerSecond):
    minInterval = 1.0 / float(maxPerSecond)
    def decorate(func):
        lastTimeCalled = [0.0]
        def rateLimitedFunction(*args,**kargs):
            elapsed = time.clock() - lastTimeCalled[0]
            leftToWait = minInterval - elapsed
            if leftToWait>0:

Three files are included:

1. `weighted_majority.py`: the weighted majority algorithm 
2. `main.py`: the main program which takes a specific beta value and make a list of plots
3. `experiment.sh`: bash script that experiments on a list of beta values. This is a good entry of this gist.
