Turn the master list layout into a LinearLayout and add a "Next" button at the bottom of the gridview

In MainActivity, based on where a user has clicked, store the selected list index for the head, body, and leg BodyPartFragments

Put the selected-image information in a Bundle and attach it to an Intent that will launch an AndroidMeActivity

Get a reference to the "Next" button and launch the intent when this button is clicked

In AndroidMeActivity, retrieve the bundled list index values that were sent through the intent and use them to display the desired Android-Me body part image
