Auction Tracker - remove bad entries

[Argh]

I can make this in PHP if theres an idea as to how exactly the pruning should work.

It appears the original intent was to allow people to "flag" a price as being outside of normal ranges for an item.

I have a person auction thingie I use that does this in an automated way by doing a standard deviation from mean calc, and throwing out things that are beyond 2 (or 2 1/2 maybe?) standard deviations. it's not perfect, espcially for illiquid items (eg: without a lot of history), but works ok

Woot, we have a volunteer for #2 (thanks Argh)!

Now we just need a consensus on #1 (how the pruning should work), and then once Argh is done someone will have to beg Rogean/Ravhin to add his code to the wiki (#3).

This would probably be the easiest way to do it, with a minimum number of entries required before it starts filtering out the outliers,
