web/examples: add table-onaggregated-data

[yetanotherion]

This commit shows how to create a table
on aggregated data. This currently works
even out of luck :), by setting a
dimension.group().reduce(...)
object instead of a dimension in the table.

More precisely, it works if the table's:

• .group() is defined, and returns the same value for all elements
• .order() is defined & defined to something else than the default value
  (which seems to be either d3.ascending or descending, a method that is
  undefined for .reduce()-d dimension groups is called else).

Thanks, this looks good. To clarify, this is for #927 and the idea is to also document that a data table can take a group instead of a dimension (and that it has a completely freakazoid idea of what a group is).

I'll fix the docs at the same time I merge this.

Updated the PR to fix typo & useless modifications of index.html
