Detailed description

The gen_pattern.py code provided to generate a chessboard/other calibration target does not output to the local directory as expected, but instead locates the output svg on the desktop. Please reference forum question here. The consensus was that either the documentation should be updated to clearly indicate that the output gets sent to the desktop rather than to the execution folder, or the code should be updated to send the output to the local execution folder.
