  This block writes vectors as JSON arrays with
  accompanying tags (vectors without tags are skipped).

  input:
    vector of complex, float, int or short.

  parameters:
    vlen: length of sample vector.

  output is of the form, line JSON object per line (describing one vector):

  {"tags": {"tag1": "value1"...}, "values": [ val, val... ]}
