workbench workflow

I got the latest version of Open Atrium Workbench module from github and used the make file with drush to bring about all the relevant modules and patches to enable me to achieve a multistage proposal submission workflow. I have a number of stages that the proposal has to go through before it gets published. The author is a researcher who creates the proposal and sets its moderation state from "draft" to "needs review by deputy director". The deputy director then has the option of either setting it back to "draft" or to "needs review by director".
