-------------------------------------------------+--------------------------
Since David Perkinson's sandpile module (for studying the Abelian Sandpile
Model; see for example: [http://en.wikipedia.org/wiki/Bak-Tang-
Wiesenfeld_sandpile] or [http://people.reed.edu/~davidp/sand/]) is already
written as a properly formatted Sage module it makes sense to include it
in the Sage library.
This module involves a variety of mathematics but it seems to make the
most sense in the graphs module.
Some parts of the module require 4ti2, currently an experimental package
(but there is no reason it can't be at least an optional package), but
this can be explained in the relevant docstrings.
In case any mathematical justification is needed, this model is of
considerable and rising interest. For example, at the joint math meetings
in 2011 there was a talk by Yuval Peres of Microsoft Research surveying
it: [http://www.ams.org/amsmtgs/2125_abstracts/1067-a0-38.pdf].
