Subject: [PATCH] GroupingGetterFunction should be allowed to return arbitrary
 value

Underlying slickgrid logic only takes into account equality between values
returned for grouping individial rows. Getter thus does not need to
return `string` but might return arbitrary value (e.g. string, number, Date).
