When creating the new stats pages for OGR, we took the opportunity
to make some major changes to the underlying database structure.
These changes will simplify the ongoing development and maintenance
of stats. Most of these changes should be quite transparent, but
there are a few things that might be noticed:

We have split the statsrun into two parts, an hourly job, and a daily
job. This (along with general code optimization that we've done on the
new system) should dramatically speed up the daily statsrun. With the
new system, we will import the log files from the master as they become
available every hour. The new results will not show up until the daily
run occurs though. New participants might be able to check for their
email in stats as soon as the first log containing work from them
arrives, though. This is something that we'll be experimenting with
once the new system is up and running.

The new system will not report 'blocks', it will report 'work units'.
The work unit for OGR is a node, so all stats will be based on how many
nodes have been checked. This is roughly equivalent to switching RC5
stats from blocks to keys.

There is no way to know exactly how much work is required for an OGR
ruler, so there will be no 'percent done' or 'percent of workspace'
reported.

Rates are also not currently implemented. They may or may not make a
re-appearance in the new system, as they are only re-stating the
number of work-units done in a different format, and have led to cases
of confusion on rc5-64 stats.
