Bazel is happier if Java/Java test roots are named 'java' and 'javatests', and
this will mean that once we create a BUILD file for
android/support/design/{widget,internal}/ we'll no longer need a custom package
specified in our build (which tends to cause build problems that manifest quite
weirdly). This commit doesn't attempt to refactor the build at all yet, and is
just a pure move.

Tab Layout
TabLayout provides a horizontal layout to display tabs. The layout handles
interactions for a group of tabs including:
- scrolling behavior,
- (swipe) gestures,
- tab selection,
- animations,
- and alignment.
The Android Developers site provides detailed documentation
on implementing TabLayout.
Design & API Documentation
Usage
The Material Design guidelines for individual tabs is done in the tabs
themselves; the TabLayout displays groups of these tabs and controls how they
interact with each other.
A TabLayout is a single row of tabs and can be fixed or scrollable. For a fixed
layout, the maximum number of tabs is limited by the size and number of the tabs
and the screen size. Fixed tabs have equal width, based on the widest tab text.
A tab layout should be used above the content associated with the respective tabs and lets the user quickly change between content views. These content views are often held in a ViewPager.
Use setupWithViewPager(ViewPager)
to link a TabLayout with a ViewPager. The
individual tabs in the TabLayout will be automatically populated with the page
titles from the PagerAdapter.
Alternatively, you can add a TabLayout to a ViewPager in XML:
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top" />
</android.support.v4.view.ViewPager>
