Shows cool scatter graphs like this!

WDL:

task foo {
  Int i
  command { ... }
  output {
    String str_out = i
    Int int_out = i + 1
  }
}

workflow scatter_test {
  Int x = 5
  Int y = 6
  scatter (s in [x, y]) {
    call foo { input: i = s }
  }
}

questions:

• Why is the s in the blue box of type Any?
• Shouldn't the s in the blue box connect to i in the white box?

@mcovarr

• That was a TODO in WDL4S. I fixed that with the fold-style WOM graph building.
  • EDIT: Updated the image.
• It's because it's an expression based input node, and the expression's input is "s".
