Creating a library, using Jaguar

The original post on creating a Toit Library was written a year ago, when Toit was only offered as closed source. Since then, the Toit language has been open sourced and Jaguar tooling added. An update of the original article, using Jaguar v1.7.1 to revise and run the project FW_Keyboard was posted as a Show and tell on Toit Discussions.
