Reviewers: zundel, daniel.libicki, Description: This is to allow using a column as if it's a java.util.List, as well as some column-related utility methods.
In our offline discussion, adding it to the open source is one alternative. The concern against adding it to open source: We don't want to increase the size of download for non-essential value-add functionalities. But from our discussion I got the impression that this may not suffer the problem because: * It's a separate class that client doesn't have to use. The core AbstractDataTabl3 has no dependency on it. When it's not used, GWT will optimize it away. * Its internal anonymous classes will be optimized away if not used. For example, if client only uses DataColumn.numbers(), the code for strings/integers/dates etc will be optimized. So I thought sending it here is still the first step since it could add some convenience for open source users.
