Although we could use print() from __future__, this messes up scripts which use examples as modules. The simple, if not nicest for 2.7, solution is to use info(), output() and other mininet.log functions. The disadvantage is that we may have to adjust things if we change info() to add automatic newlines, but we can burn that bridge in Mininet 3.x.
