What is a Crossfilter group?
From reading about the [Crossfilter](http://crossfilter.github.io/crossfilter/) data manipulation library for JavaScript, I take it that "groups" are an important concept in its operation. However, the Crossfilter [documentation](https://github.com/crossfilter/crossfilter/wiki/API-Reference#group-map-reduce) does not ever define the concept. Assuming the word is being used in a similar sense to the common English or mathematical uses, the group will contain members or elements, and be defined by what these elements are (their type, and how they're selected for membership in the group). Is this the case, and if so what are the elements of a Crossfilter group? What is their type (`crossfilter` objects, `dimension` objects, `record` objects, primitive types, arrays and objects formed from the these, etc.)?
