Version 1.1.1 – Fix SVG file for SBML badge
It turned out that the SBML badge was not being displayed in the README file on GitHub, although it did display in local testing. It's unclear why; my best guess is that the SVG file contained needless complication introduced by Adobe Illustrator and perhaps this ran afoul of some of the SVG sanitization steps used by GitHub. The new version of the SVG file appears to work on GitHub.
