gantty:0.5.0

[John-Toohey]

I am submitting

• a new package
• an update for a package

Changelog

Added

• Task dependencies under the dependencies field.
• Drawers API to allow complete customization of various parts of the Gantt
  chart. This decision was made because there are many different ways of drawing
  dependencies (and, in fairness, many other parts of the Gantt chart) and
  because it will integrate better with show/set rules when they are available
  for custom elements.
• The drawers.default-drawer dictionary containing the default drawer
• An x field to intervals, tasks, milestones, and dependencies: to facilitate
  adding custom descriptions for custom drawers.
• Expose the following functions under the util namespace: EPSILON, rects-intersect,
  content-if-fits, task-anchor, task-anchor-line, task-anchor-sidebar,
  id-level, styles-for-level, styles-for-id, foreach-task, task-start,
  task-end, gantt-range, date-ratio, date-x-coord, and date-coord.
• Ability to provide a function to change how the sidebar items are styled.
• Hide a milestone's date with milestone.show-date.

Changed

• The taskgroups key is now tasks
• The tasks key is now subtasks. All tasks can have subtasks.
• Tasks are now drawn with rectangles, not lines.

Fixed

• Poor normalization of the today milestone

Removed

• The style key.
• The viewport-snap key. Specify a start and end date instead.
• Nameless tasks.
• The show-today and today-localized keys. These should be configured on the
  milestone drawer instead.
