find branch

the find.module in the branches directory is now fully functional (i think). feel free to reference the code in there to modify the trunk version.

now we need to finish the simpletest modules. we need one for each of the modules we are using in our site (mixcd.module, searchid.module, find.module). i think if we look at some of the example code that came with simpletest, we can use it to our advantage (especially the node test for mixcd, etc).
