Running atscc2js in the browser

[gmhwxi]

Now atscc2js (which compiles the C code generated from ATS source into
JavaScript) can be run inside the browser:

https://ats-lang.github.io/EXPERIMENT/test_libatscc2js/test_libatscc2js.html

This means  that all the major steps needed for compiling ATS to JS inside the
browser are done. We just need to build a nice web presentation for it.

Cheers!
