Lab-Volt data file reader

reads a "tbl"-file - the data table file recorded (and encrypted) by Lab-Volt

It turns out that the Lab-Volt, while being an excellent data acquisition system, produces data files that are incompatible with any software.
This function reads a "tbl"-file - the data table file recorded (and encrypted) by the Lab-Volt data acquisition software and imports its contents in to the MatLab environment.
