Add a description column to be used as test name or comment to describe what each test does

[bizz84]

Currently, AcceptanceMark does not provide a way of describing what each test does. It would be useful to add a description column to describe what the test will do. Example:

year:Int	month:Int	day:Int	language	dateStyle		localizedDate		description
2016	9	16	en	short		9/16/16, 5:30 PM		formats the date in English
2016	9	16	fr	short		16/09/2016 17:30		formats the date in French
2016	9	16	it	short		16/09/16, 17:30		formats the date in Italian

One way to do this is to add an additional optional column separator after the outputs. The additional description column could be used to name the test so that the generated method could change from this:

func testDateFormatting_row1()

to this:

func testDateFormatting_row1_formatsTheDateInEnglish()
