+Initial SVN commit plus:
+        - Added indala demodulation algorithm - full documentation on https://www.lafargue.name/proxmark3/
+        - losim should also be able to simulate an indala tag after indalademod
+	- offline mode for the proxmark3 CLI: if no Proxmark is detected, it will
+	  still go on, but all commands requiring USB will fail (obviously).
+	  A proper implementation would require only enabling offline commands
+	  in this mode.
