v0.10.0

• fix canonicalization problems and related issues introduced or not addressed
  in 0.9.11, including:
  • (#1361), (#1232), (#1239 (partial))- Broken links in enums
  • (#1345) and (#1090)- Reexports have wrong links in many places
  • (#1341), (#1197 (partial)) - Duplicate docs still in some cases
  • (#1334) - Some classes don't list their subclasses
  • Inheritable class members had incorrect canonicalization in many cases
  • ... and many other unfiled bugs relating to inheritance and duplicate files.
• Dartdoc no longer creates documentation for a given identifier more than once.
  This means dartdoc is 20-30% faster on complex packages.
• --auto-include-dependencies is now recursive past one layer (#589) It now drills
  all the way down and will dive into the SDK and other packages.
• Change display of warnings to be more consistent; warnings now always
  go to stderr and are printed on their own line.
• Dartdoc now warns when it is unable to find a canonical object to link to
• Dartdoc now warns if a package exports an identifier so that it is
  ambiguous which one should be treated as canonical
• Dartdoc now has a number of asserts in checked mode for issues solved
  and as-yet-unsolved, including (#1367) or canonicalization problems; try
  running in checked mode if you see structural problems in generated docs and
  see if an assert fires.
• Dartdoc internals have changed significantly:
  • Package now owns the calculation of recursive dependencies with a factory
    constructor, Package.withAutoincludedDependencies.
  • ModelElements and Libraries now have Package-scoped caches.
  • ModelElements and their subclasses now must be constructed from a single
    factory, ModelElements.from
  • Package has new methods to assist canonicalization, including
    findCanonicalLibraryFor and findCanonicalModelElementFor.
  • New mixin "Inheritable" helps class members calculate canonicalization
    for inheritable members
• change order of library, class, and enum members on displayed pages (#1323).
• change order of categories when using --use-categories, prioritizing
  this package first, the SDK second, packages with this package's name
  embedded third, and finally all other packages. A new flag,
  --category-order, lets you change what order categories appear in. (#1323)
• fix broken masthead links in enums (#1225).
