Generalize removal obvious outliers

[erictleung]

I've removed a couple outliers already, but here I want to add a function to remove other obvious outliers.

A list of some things to look for:

• Part 2
  • ExpectedEarning == "xxxxx"
  • MoneyForLearning has more than three zeros, look at two or more
  • Age == 120
  • Gender Other has some non-relavent answers
  • ChildrenNumber > 50
  • Income > 100,000,000
