/**
* Takes a text block of Outlook-exported Comma Separated Values and tries to
* parse that into individual events.
*
* First line is field names, all quoted with double quotes. Field names are
* locale dependendent. In English the recognized field names are:
* "Title","Start Date","Start Time","End Date","End Time","All day event",
* "Reminder on/off","Reminder Date","Reminder Time","Categories",
* "Description","Location","Private"
* Not all fields are necessary. If some fields do not match known field names,
* a dialog is presented to the user to match fields.
*
* The rest of the lines are events, one event per line, with fields in the
* order descibed by the first line. All non-empty values must be quoted.
*
* Returns: an array of parsed calendarEvents.
* If the parse is cancelled, a zero length array is returned.
