1.0.0-beta.37 (18-05-2020)

Extended prepare handler to take extension API as a second parameter. For now API contains following methods:
- addValueAnnotation() to define a value annotation used mostly in struct view. The first argument should be a handler: a function or a string query. Handler takes a value and context, which contains properties: host (an object or an array that includes a value), key, index and parent (a reference to parent context). The handler should return falsy value (when no annotation needed) or an object with following fields (all fields are optional):
  - place – 'after' (by default) or 'before', where to place annotation before or after a value
  - style – 'default' (by default), 'none' (no any visual styles for annotation block) or 'badge' (uses for object markers)
  - className - additional CSS classes that should be added to annotation block
  - text – annotation text
  - title – value for title attribute
