Merge strategies for streamson-bin

[shenek]

Try to think of a way how to merge output of two (or more) JSON streams using streamson-bin. First stream:

{"name": "carl"}
{"name": "bob"}

Second stream:

{
  "users": [...]
}

-> (with {"users"}[] matcher)

{
  "users": [{"name": "carl"}, {"name": "bob"}]
}

For starters streamson could be able to merge all input jsons into an arrray.
