names
How do duplicate column names work? If you look it up by name, you get the
last one? But each gets an index?
So if I had 2 columns named "Foo", the Count would be `2`, and index 0 would
be the first column. Index 1 would be the second column. And if I said
`schema.GetFieldByName("Foo")` I'd get the 2nd column?
