A port of the web-based software 'DAGitty', available at
<http://dagitty.net>, for analyzing structural causal models
(also known as directed acyclic graphs or DAGs).

implications (d-separation and vanishing tetrads), generates equivalent
models, and includes a simple facility for data simulation.
