Adjusting Sample Applications

As noted in issue #67 the default methodology of the sample apps required adjustments to the Rakefile.  I've adjusted the "Hai" example to natively house the styles.

The Autolayout example houses the styles for the app inside the app folder, and uses the lib folder delineation for imported styles.  This still requires the addition to the Rakefile, but follows a structure that should imply intention to the user.
