So I was watching an MIT lecture on algorithms, and they were talking about 
the quicksort, so I decided I should revisit it in haskell now that I have 
a little more experience.  The common example you see has issues with repeated
work.  I attempt to minimize this me avoiding list concatenation and 
using a partition instead.

I used literate Haskell because I plan to add better annotations later.

    JSONParser.hs
    Version 0.1.1
    
    A simple example of parsing JSON with Parsec in haskell.  Note that 
    since the primary point of this excersize is demonstration, 
    Text.Parsec.Token was avoided to expose more of the grammar.  Also,
    complicated optimizations and shorcuts were avoided (mostly).
