v2.0.0

• Mappers are now generated for each file containing annotated classes. This removes the
  need to specify entry points in the build.yaml.

  This is now similar to how packages like json_serializable or freezed generate code.

  • Generated files are now part files and need to be included as such.
  • All annotated classes must now use their respective <MyClass>Mappable mixin.
  • Instead of one global Mapper each class has its own <ClassName>Mapper.
    • A new global container that includes all models can now be generated using
      @MappableLib(createCombinedContainer: true).
  • Mappers can be linked together to enable working with multiple classes.
  • Removed @CustomMapper annotation in favor of includeCustomMappers property on @MappableClass().

  For a detailed migration guide, see this issue.

• Documentation is now separated from the README using the official pub.dev documentation topics.

• Improvements in performance and support for generics and inheritance.

• Added the [CheckTypesHook] to allow for custom discriminator checks on subclasses in a
  polymorphic class structure.

• CopyWith is now more powerful and also works for generic or polymorphic classes, while being
  completely type-safe.

  When called on a superclass, the concrete subtype will be retained through a
  .copyWith call, which also respects generics:

    // with `class A` and `class B<T> extends A`
    A a = B<int>(); // static type A, dynamic type B<int>
  
    // signature will be `A copyWith()`, so static type A
    A a2 = a.copyWith(); 
  
    // this will still resolve to a dynamic type of B<int>
    assert(a2 is B<int>);
