Have each group member fill in the functions that they were assigned. (I will fill in the unassigned ones, as well). They should do this in their own branches of trunk. Branches can be made in xcode using the copy command in the Repositories window. The project file, when opened, will automatically know that it's a branch and will commit to the correct branch directory.

Please test the trunk code on any platforms that you have access to, so that we can e-mail fardad with news of our completion.
