QSDualTileLabel

public class QSDualTileLabel extends android.widget.LinearLayout
Text displayed over one or two lines, centered horizontally. A caret is always drawn at the end of the first line, and considered part of the content for centering purposes. Text overflow rules: First line: break on a word, unless a single word takes up the entire line - in which case truncate. Second line: ellipsis if necessary
