#   get_projects
#                     Determine list of projects and returns to
#                     list to idev for user selection as the default.
#                     Unfortunately, if the user had only one project
#                     the project is not returned. Uh!  So, use_default
#                     is returned to idev, which then uses a blank
#                     for "-A <project_id>" in the job scripts.
#                     After all is done, the project name is placed
#                     in $HOME/.idevrc for subsequent use, obviating
#                     the need to call get_projects again
