publish ttools to maven central

[pahjbo]

now that the the stil library has been published to maven central (#54) - it would be nice if the ttools library could be published too for the people who want to use the graphics in their own applications.

Hi @pahjbo. The external dependencies are way more complicated for ttools than for STIL, so I think it would take quite a bit of effort. You can get some idea of what's required from the ttools LICENSE.txt. Although I agree it would be a nice-to-have, I don't anticipate doing this, at least unless there seems to be overwhelming demand.

It is a shame I am probably one of only a few people who use the graphics library in applications.

For what it's worth, the output below is the dependency tree from my maven build - the dependencies that start uk.ac.starlink-third are libraries that either were not published to maven central, or you had explicitly mentioned that you had patched. This reflects the situation several years ago when I did the build, so some of these libraries might have been published by their authors by now. I don't think that it would be "illegal" for you to publish them in a similar way under say a uk.ac.starlink.third-party group too
