 * owondump.c  0.3		A userspace USB driver that interrogates an Owon
 * PDS digital oscilloscope and gets it to dump its trace memory for all
 * channels, in both vectorgram format, and/or in .BMP bitmap format.
 *
 * 				The vectorgram is also parsed into a tabulated
 * text format that can be plotted using GNUplot or a similar package.
 *
 * 				The code now has an elegant decodeTimebase
 * function, courtesy of Michel Poullet!
