    layout: add transient sidebar class
    
    This is going to be our base-class for a transient sidebar. It
    will be used in the editor, but possibly other perspectives such
    as the debugger.
    
    The purpose is for it to be smart enough to transition in/out as
    necessary based on some set of conditions.
