Stuff for actually building the pools.

std2robot.pl makes gwl files that drive the cherry-picking robot
to produce the micro-pools.

It generates those files in CommandFiles_tmp/ (currently empty),
the content of that dir after running std2robot.pl will be
essentially identical to those in CommandFiles/, which are the 
command files that we used.
Superposing/ holds an excel file which describes how the
micro-pool plates were superposed to generate the various
smart-pool plates.
