A CSV row with or without headers. The presence of headers is encoded via the first type param which is a subtype of scala.Option. By preserving this information in types, it's possible to define Row and CsvRow aliases as if they were plain case classes while keeping the code DRY.
Operations on columns can always be performed using 0-based indices and additionally using a specified header value if headers are present (and this fact statically known).
Note: the following invariant holds when using this class: values and headers have the same size if headers are present.

Concrete methods
Returns the content of the cell at header if it exists.
Returns the content of the cell at header if it exists. Returns None if header does not exist for the row. An empty cell value results in Some("").

Returns the decoded content of the cell at header.
Returns the decoded content of the cell at header. Fails if the field doesn't exist or cannot be decoded to the expected type.

Returns the decoded content of the cell at idx.
Returns the decoded content of the cell at idx. Fails if the index doesn't exist or cannot be decoded to the expected type.

Returns the decoded content of the cell at header wrapped in Some if the cell is non-empty, None otherwise.
Returns the decoded content of the cell at header wrapped in Some if the cell is non-empty, None otherwise. The meaning of _empty_ can be tuned by setting providing a custom isEmpty predicate (by default, matches the empty string). In case the field does not exist, the missing parameter defines the behavior (by default, it faile) Fails if the index cannot be decoded to the expected type.

Returns the row without the cell at the given header.
Returns the row without the cell at the given header. If the resulting row is empty, returns None.
**Note:** Only the first occurrence of the values with the given header will be deleted. It shouldn't be a problem in the general case as headers should not be duplicated.
