### Arguments

`from` | either Tool App or Workflow object
`to` | either Tool App or Workflow object
`...` | more auguments
`id1` | id to be connected from the ouput of the first node
`id2` | id id to be connected from the input of the second first node
`flow_id` | workflow id, if ignored, going to create one by joning tool id.
`flow_label` | workflow label, if ignored, going to create one by joning tool labels.
`flow_input` | full flow input id, e.g. "#SBG_Unpack_FASTQs.input_archive_file"
`flow_output` | full flow output id, e.g. "#STAR.log_files"

### Details

Flexible enought to allow users to connect two objects by ids

### Value

A Workflow object

### Examples

    t1 <- system.file("extdata/app", "tool_unpack_fastq.json", package = "sevenbridges")
    t2 <- system.file("extdata/app", "tool_star.json", package = "sevenbridges")
    t1 <- convert_app(t1)
    t2 <- convert_app(t2)
    # check possible link
    link_what(t1, t2)
    # link
    f1 <- link(t1, t2, "output_fastq_files", "reads")
    # link
    f2 <- link(
      t1, t2, "output_fastq_files", "reads",
      flow_input = "#SBG_Unpack_FASTQs.input_archive_file",
