switching to a project should: 
    Save all of my current work
    Clear out the work space
    Set up the work space to new project
    load in backup (if selected)
    PopUp Sublime Project, if exists and if selected

Saving an Image should 
    allow for a short description
    save to a subfolder in .ImageSaves based on current wrkDir & projName
    +  write to a file details of the environment.
       (ie, description plus lsos output, where functions are optional. Perhaps allow for short & long descriptions)    

Loading an Image should
    optionally run fresh first
    default to the newest
    offer options to see some info and more details, 
      where some info would include: date, size, description (short)
      and more details would include above plus lsos() info & long.description. 

Cleaning Images should
    default to "current project" but optionally allow for "whole folder" or a vector of project names
    For each project, display all the short-info that is grabbed when loading the project and offer that info for confirmation of deleting. 
    Clean the 'tracking file' (if such a file is implemented)
