Implement JSON pointer (built-in) and manual pointer treatment with two examples (JSON pointer and relative JSON pointer)

- Changed error message for invalid redefinition

- Also add some tests for left direction

use direct field access instead of getter to reduce unnecessary dependency creation when using incremental evaluation

check uniqueness during serialisation, fix nullpointer issues in rewrite checks, add test for node removal

Add flag `--useJastAddNames` generate names in the form of addX, removeX and setX. If omitted, relast will default to the original naming scheme addToX, removeFromX and setX.

make unresolved subtypes of abstract types abstract, use unresolved interface. rename resolver methods (for MQuAT compatibility)

add resolveAll and treeResolveAll functionality to ensure all references are resolved (important for bidirectional references)

- "addToX" -> "addX"
- "removeFromX" -> "removeX"
- "x()" -> "getXs" and "getXList"

add option to rename list class. this made it much easier to use the generator in the train benchmark.
