Refactoring and normalization of boolean statements

[jjmaestro]

The initial structure was:

if a:
    if b:
        print '1'
    else:
        print '2'
else:
    if b:
        print '1'
    else:
        if c:
            print '3'
        else:
            print '4'

which can be clearly simplified to

if b:   
    print '1'       
elif a:
    print '2'       
elif c:
    print '3'
else:
    print '4'

Thus, the refactor :) In my opinion, it simplifies the whole conditional flow quite a bit and that's always nice :D
