CoCoA » CoCoALib

I still have some warnings, but it compiles and works fine

This was likely caused by different translation units being compiled with different visibility settings.

On my MacBook I get over 100000 (one hundred thousand) lines of warnings when compiling.
I think there is some mild incompatibility between BOOST and the compiler (g++ on MacOS)

My proposal in note 5 is not unreasonable, but is it really KISS?
