Add script to deal with SVG files per sample

replace_svg_object.py is capable of takinga directory with files
formatted and created by EMPeror.
Add tests for format.py and clean code

Remove unnecessary print statements and add exception ceration for the
main function that replaces and formats the SVG file.
Update credits
Change replace_svg_object.py to be per-sample

The script now works on a per-sample basis, this means that it can be
run in parallel for each of the samples that need a figure generated.
