/**
* JSON Merge Patch implementation
*
* This is a complete implementation of RFC 7386 (JSON Merge Patch).
*
*
* You may want to use this instead of a "pure" (aka RFC 6902) JSON Patch if
* you want to do simple patching of JSON Objects, where this implementation
* really shines. For instance, if you want to replace a value for one
* property {@code p} with JSON String {@code "bar"}, a JSON Patch will read:
*
*
*
* [
* { "op": "replace", "path": "/p", "value": "bar" }
* ]
*
*
* whereas the equivalent JSON Merge Patch will be:
*
*
* { "p": "bar"}
*
*
* Note that this is recursive; therefore, this:
*
*
* { "a": { "b": "c" } }
*
*
* will replace (or add, if not present) the value at JSON Pointer {@code
* /a/b} with JSON String {@code "c"}.
*
* HOWEVER: while this seems attractive, there are a few traps. One
* of them is that, when a value of an object member in a JSON Merge Patch is
* a JSON null, the target will see the equivalent member removed; there
* is no way to specify that a value should be set with a JSON null value (JSON
* Patch allows for this).
*
* The RFC defines a pseudo code for how a JSON Merge Patch is applied; this
* function is replicated in the javadoc for {@link
* com.github.fge.jsonpatch.mergepatch.JsonMergePatch}, so you are encouraged to
* read the javadoc for this class, and the RFC itself.
