Create repository of libraries for the HEADS Modelling language

[brice-morin]

Create a lightweight Maven- or NPM-like repository for HEADS artifacts so that models can be more easily constructed by importing other models from the standard HEADS libraries (timers, serial, etc).

I guess we can put those libraries in a separate GitHub repository and enable the import mechanism in ThingML to import from GitHub (or any HTTP address), a bit similarly to what golang proposes.
