cast: Dynamic type cast failed. Expected: String. Actual: Nil #186

I've got a CSV which has an empty string in its header:

"","term","estimate","std.error","statistic","p.value"

Which makes cassava bail out:

cast: Dynamic type cast failed. Expected: String. Actual: Nil

IMO cassava should generate an empty String as header here.

Wrong library.
