'DOM' Version 0.3

This report describes changes in version 0.3 of the 'DOM' package for R. This version represents a major refactoring of the package code, including its user-facing API. These changes were made in order to facilitate the addition of new features to the package, which in this version include: a new way to refer to DOM nodes from R code that allows building web page content "off screen"; and greater flexibility in how requests are made from R to a web browser and vice versa.
