* Add build command for Markdeep files build.sh -w can now be used to "rasterize" Markdeep .md.html files to regular, static .html files. These files load faster and do not suffer from an initial flash of uninitialized content. This new command requires node, npm and nx to run puppeteer to "rasterize" the Markdeep documents. This should eventually be integrated in the actual build system to automatically re-generate the HTML files when the Markdeep documents are edited. * Remove unnecessary .gitignore file * Change constant names for JS docs
