Plugin: Merge data

[atompie]

Is your feature request related to a problem? Please describe. The same plugin as copy data but it merges data instead of coping it.

Lets assume that our profile has the following traits

{
   "public": {
       "a":0,
        "c": 3
    }
}

We define:

{
  "profile@traits.public": {
   "a":1,
   "b": 2
  },
"profile@traits.public,my": {
   "d": 4
}
}

and get

{
   "public": {
       "a":1,
       "b": 2,
        "c": 3,
        "my": {
            "d": 4
        }
    }
}
