wea.table_filter: add API function
Really, Lua should have this already. At this rate, I'll be implementing 
the entire Javascript standard library... :P

//subdivide: tally total times so far as we go
- Don't use wea.sum() on a table full of all the times we've recorded
   so far
 - Limit individual stats list lengths to 25 to avoid memory issues when
   running with a large number of chunks
 - Tally total times / metrics as we go to avoid memory issues

//erode: Finish the initial round of bugfixing, but I'm on the fence about it.
Specifically, I'm unsure about whether I'm happy with the effects of the 
algorithm.
Also, we convolve with a 3x3 gaussian kernel after erosion is complete - 
and we have verified that the erosion is having an positive effect at 
"roughening up" a terrain surface.
It seems like the initial blog post was correct: the algorithm does tend 
to make steep surfaces steeper.
It also appears that it's more effective on larger areas, and 'gentler' 
curves. THis might be because the surface normals are more conducive to 
making the snowballs roll.
Finally, we need to decide whether we want to keep the precomputed 
normals as we have now, or whether we want to dynamically compute them 
at the some of request.

Start implementing snowball erosion algorithm.
There's still a long way to go - we're only just getting warmed up!
