Widget derive macro

The Widget (and DataProcessor) trait will be automatically implemented for the structure.

There is few attributes which will help you to configure the implementation.

#[base_widget]

Exactly one structure’s member with implemented Widget trait have to be marked by the attribute. All Widget stuff will be delegated to the member.
