Renewed my Python interest: started watching Python Bootcamp, installed Anaconda, and now pythoning with TextMate!  Bye, bye to PyDev & Eclipse.  Updated the integer and fixed-point learnings.  See the added comments.
Updated the docstring for fxp function in fxp.py.
Added binomial_ipydemo.py to plot binomial distributions.  It also contains nifty ways of computing combinations i.e. nCr.  Minor updates to docstrings of ipydemo.py and gaussian_ipydemo.py.
Minor improvement to how golden ratio progression is printed.
