- Remove Jorje dependencies
- Add temporary local jar dependency for Summit-AST
- Comment out code until compilation succeeds

- Replace `ApexNode` type arguments with `Void`
- Remove `ApexNode.getNode`
- Remove `ASTCommentContainer` type parameter
- Deprecate `ASTUserClassOrInterface` type parameter

Remove `node` field from `AbstractApexNode` to remove restriction of
wrapping a single node. Create `AbstractApexNode.Single` subclass that
wraps a single node.

Other subclasses can be created as needed for common cases, or
`AbstractApexNode` can be extended directly in irregular cases.

- Add call to `SummitAST` in `ApexParser`
- Fix NPE involving `suppressMap` to allow `ApexTreeBuilder` to run
- Remove unused `TopLevelVisitor`

Replace `CompilationUnit` with `TypeDeclaration` as the top-level node
to match the AST produced by Jorje.

- Replace `ApexTreeBuilder.java` with `ApexTreeBuilder.kt`
- Set up tree builder foundation
- Build `TypeDeclaration` nodes

- Add `AbstractApexNode.Many`

- Add `buildChildren` function to tree builder

- Split `setParent` call from main `build` function into new
  `buildAndSetParent`
- Remove list-based `build` function to decrease complexity
- Improve documentation
