this is the first checkin for the new mapping lib, which is a join effort of Cyrille and Hans. We are combining Cyrille's ds_/datastream classes with my hid_* classes, and I think Cyrille has drawn on the La-Kitchen classes for working with sensors.svn2git-root

+
+This is the beginnings of the "mapping" library, which is a combination of
+efforts of Cyrille Henry and Hans-Christoph Steiner.  It draws from the hid_*
+classes, ds_/datastream classes, and the La-Kitchen classes for working with
+sensors.
+
+These classes are for creatively mapping data to something that you want to
+control.
