  Some changes per team review of project templates feature. Added a new server API cmd/getProjectTemplates to pull down list of project templates (which hopefully will allow us to get rid of project template list from getInitializationInfo). Includes a searchString feature and a limit feature on max# of items returned. Added a new client function to invoke cmd/getProjectTemplates *asynchronously*. Changed ManageProjectTemplates.js to use the new server API and the new async client side function. Still more to do to eliminate project templates from getInitializationInfo.
