Version 3.1.0-beta.2
------------------
This version is a beta because `TreeStructureVisitor` is not in its definite state yet.

* 762 761 772 merge `javaparser-metamodel` and `javaparser-generator-utils` into `javaparser-core`.
* 766 the `ModifierVisitor` is now created by a code generator. Its behaviour has been made logical, and may give different results than before.
* 755 `ConstructorDeclaration` and `MethodDeclaration` now share a parent: `CallableDeclaration`
* 687 759 773 769 768 767 765 759 smaller improvements and fixes

Version 3.1.0-beta.1
------------------
This version is a beta because there are a lot of new features that may still change.

This version needs a minor version increase because of a backwards compatability issue: 
* 719 `getJavadoc`, `getJavadocComment` and `getComment` could return null. Our promise was to return `Optional`, so that is what they do now.

New:
* 658 718 736 737 we have created a metamodel.
It gives information about the structure of the various AST nodes, as if you are introspecting them.
You can find it in `javaparser-metamodel`, the main class is `JavaParserMetaModel`
* 353 365 visitors are no longer hand made, they are now generated from the metamodel. This should make them 100% reliable.
Affected visitors are: `GenericVisitorAdapter`, `EqualsVisitor`, `VoidVisitorAdapter`, `VoidVisitor`, `GenericVisitor`, `HashCodeVisitor`, `CloneVisitor`.

If you want to generate your own visitors, you can use the `VisitorGenerator` class from `javaparser-core-generators`

If you want to reuse the code generation utilities, look at module `javaparser-generator-utils` - there is a very useful `SourceRoot` class in there that takes away a lot of file management troubles.
* 538 735 `TreeStructureVisitor` has been added, which should be considered beta.

Version 3.0.0-alpha.4
------------------
* 463 471 nodes can now be removed easily
