Initial version of the csv2vbo.py script.
Updated README.md to provide basic information about csv2vbo.py.
Added support for exporting the user-define and longitudial acceleration channels.
These may come from actual accelerometers instead of being calculated from GPS coordinates.
Added filtering of potentially duplicate header lines when reading input files.
Moved duplicate row filtering from output into transformation code.
Moved fudging of the "satellites" channel into transformation code.
Simplified VBO header calculation and channel unit collection in transformation code.
Separated formatting from conversion, so that intermediate processing steps can be added.
Added support for interpolating values between adjacent rows if their times differ by more than 0.1s.
This simulates a 10Hz GPS for the CircuitTools software, but by no means provides the accuracy of real 10Hz GPS.
