Added a more flexible way of using groups that does not necessarily need columns to be grouped by. Also the specified groups will be displayed no matter if there are items or not (like with the remoteGroups). So the main purpose that we needed is:
Display a predefined structure of groups, no matter if there are rows or not
React on opening the group, load rows from a server and add it
This is now possible for us with the method setCustomGrouping(), the "groupheaderclick" event and with custom getters and formatters. I added an example to show how we are going to use the feature.
