The source project of this merge request has been removed.
Added JSON Pointer support
JSON Pointer is defined by RFC 6901. In contrast to JSONPath being a powerful tool, JSON Pointer is very simple and allows to select a single node. However, it is used by JSON Schema, which I want to implement as soon as this gets merged.
One might notice that there is much copy-pasting from json-path* here. That's why I put both copyright notices in new files.
