Test cases for the scenarios described in SANDBOX-161:

* Double quotes (") should be escaped using two double quotes (""), rather than a backslash (\").
* Embedded line breaks are allowed and don't need to be escaped... just enclose the field in double quotes.
* Because backslashes are not used to escape double quotes or line breaks, the backslashes themselves do not need to be escaped.
