release-0.2

This release contains an example of embedding the interpreter into some random code:

• The file embed/main.go does a couple of things:
  • Defines a DOT function implemented in go that will set a pixel on a PNG canvas
  • Defines a SAVE function to write out that pixel
  • It also defines PEEK & POKE functions, which are less impressive.

Otherwise there are some new primitives RND, PI, SQT, etc. These primitives are implemented using the extension-mechanism the embedded example demonstrated.

The final remaining new feature was the migration to storing variables as float64 rather than int, which was necessary to store values such as π.
