I am happy to use this "rainbow", though please show me how to install and use it initially [new to github] thanks in advance :)

It's fine being new to stuff. If you try clicking the link, there's installation instructions there:

To download and build rainbow and open a REPL:

   git clone git://
   cd rainbow
   ant           # yes, twice. The second time uses rainbow to generate optimisations of itself
   cd src/arc
   java -server -jar rainbow.jar
