It seems to me that the mode calculation is now available in `r.mode`, so

there is no reason to keep `r.statistics`. Since it is removal of a

module, we might not be able in version 7 unless somebody has some idea

how to do it without breaking the interface.

In the meantime, we should remove links to `r.statistics` from other

modules, improve their documentation (`r.statistics` has better docs then

the other modules), and put some info to `r.statistics` that is is

depreciated (we probably don't have a clear way how to do that). This

might be nice to have even for 7.0.4, so if somebody volunteers to do

that, it would be great, I won't get to this in the following weeks.

Finally, we should be checking if `r.statistics` can be really removed. If

somebody is using it, please speak up.
