• Removes backwards compatibility for unquoted expressions (e.g. exclude src -> dest - use exclude "src -> dest" instead).
• Adds the ability to include/exclude relationships by the tag of source of destination elements (e.g. exclude "* -> element.tag==Tag").
• Adds support for directory based includes with !include.
• Adds support for element expressions to be used in the afferent/efferent coupling expression (e.g. exclude "->element.tag==Tag")
• Adds support for element expressions of the form element.parent==<identifier>.
• Fixes #113 (Excluding relationships with tags in a Deployment Diagram).
