Template:Reflist/sandbox2/doc

This is a candidate to replace reflist. It does not implement a fixed number of columns, so substitutes the following: In addition, it implements the following presets for colwidth:
 * 1 as 200em
 * 2 as 30em
 * 3 and more as 25em
 * normal equivalent to 30em
 * narrow equivalent to 25em

Otherwise, it implements group, refs, colwidth and 30em etc. as Reflist usually does.
