Let's write a function that takes a FieldStorage, and returns back an
equivalent dictionary:

###
def fieldStorageToDictionary(fs):
    mydict = {}
    for k, v in fs.items():
        mydict[k] = v.value
    return mydict
###

To tell the truth, I haven't tested this code yet, but hopefully this is
close enough that it'll help you write that function.  Good luck!
