A port of impress.js by @bartaz to Elm

The software is usable. It is as simple as creating a declarative list of steps in a separate Elm file, wiring it up in the Main module. In Elm terms, each step is defined as a record type with default values, and ends up being turned into an Html type by the elm-impress engine.

See the Demo folder for an example, taken from the official impress.js demo.

To compare, try the elm-impress demo.

• Describe differences vs. the original JavaScript version (very few indeed, and minor too)
