Auto-added Android Dependency frobbit.
Doc Comment.
Merge branch 'master' of github.com:androidcook/Android-Cookbook-Examples
This version works, but still displays huge long spaces on each.
Use adapter's CursorToStringConverter(): better, but not product-ready.

Converter uses String.format() to format the final product, but matching
choices in  portrait format still have huge trailing spaces (5-8
lines!!); in landscape mode the converter is called and a few choices
are displayed (by the Inputm Method?).
Document and re-indent the getEmailAddresses() method.
Don't call getContentResolver on every keystroke (micro-optimization?).
Make some things final and/or static that can be.
