Documentation request- seqcol without sequences

[mikelove]

Can you provide an example of canonical seqcol object representation when sequences are not provided, as in F4.

Do you leave off the sequences entry or do you digest the empty string or other?

Ok, I'll add that. basically you just don't include the sequences attribute at all. (no digested empty string)

I added an example to the spec:

{
  "lengths": [
    "1216",
    "970",
    "1788"
  ],
  "names": [
    "A",
    "B",
    "C"
  ]
}
