Docker image

[bmxam]

Hi,

It took me a few hours to succeed in compiling polyquad. It seems (but I may be wrong) that polyquad is not compatible with the latest version of Eigen (5), that it necessitates a relatively recent version of Boost (but which one exactly?), and a relatively recent version of clang. And it does not compile with the versions of these libraries obtained with apt-get install (...) on Ubuntu.

Once I succeed, I built a Docker image that could help occasional users to use the library without having to compile anything. Will you be interested in a PR where I add the Docker description in the README for instance? Or would you like me copy it right here so that you can publish an "official" Docker image?

Side remark: this is a very basic image: no MPI, quite large (~4GB) but it's working

It is probably more useful to update the code/build system so that a Docker container isn't needed. Specific things on my list are:

• The CMake file needs updating.
• Compatibility with newer eigen releases.

In terms of Boost version anything from the last 6 years should work. Similarly, any version of Clang from this decade will do the job.

I've pushed a few tweaks to resolve some of the lingering issues. The issue with Eigen 5 is due to boostorg/multiprecision#744 and requires a fix on the Boost side.
