First step in fixing issue #3157 is to check-in the source code and hook it into our build system. The inclusion of the MuParser source adds the MIT License to those that apply to fish. Update our documentation to reflect that fact. The MuParser documentation is at http://beltoforion.de/article.php?a=muparser. The source was downloaded from https://github.com/beltoforion/muparser/releases. It is also hosted on Github, https://github.com/beltoforion/muparser/. I did not download it from Github because that source contained just a couple of cleanup changes which don't affect its behavior.
