+%%%% Stacked labels

+% stacked labels by Romano Giannetti romano@rgtti.com
+% heavily based on Claudo Fiandrinos's https://tex.stackexchange.com/a/65792/38080
+% \expandafter trick inspired by Matthew Leingang's https://tex.stackexchange.com/a/12272/38080
+%
+% labels are in a tabular, globally aligned:
+%        vertically with key l2 valign (default c)
+%        c: center t: top b: bottom
+%        horizontally with key l2 align (default l)
+%        l: left c: centered r: right
+% you can switch sides using l2_=... and l2^=...
+% syntax is l2_ = line1 and line2 (same for l2^)
