Extra text and code in week3/montecarlo.Rmd

[jmcastagnetto]

The text and code from line 106 (https://github.com/genomicsclass/labs/blob/master/week3/montecarlo.Rmd#L106) up until the end of the file, does not seem to belong there (at least it is not used/mentioned in the lecture videos). They might be remnants of an alternative example for the "Inference" and "Permutation" lectures.
