Custom type converters

All 13 scenarios passing

A static @TypeConverter method in the test class decides what a cell's text becomes, so a table can speak the domain's language instead of programmer literals. Three converters serve the tables below: Yes/No becomes a boolean, a number word becomes an integer, and a day word becomes a date. The rules are written so the conversion itself stays visible. Each table pairs the text as written in the cell with the value the test method received, printed back as plain text — a String column no converter touches, and therefore one that shows what the converter produced instead of restating what it was given.
