class_docstr: Singleton to manage a set of integer-numbered figures.
  
  This class is never instantiated; it consists of two class
  attributes (a list and a dictionary), and a set of static
  methods that operate on those attributes, accessing them
  directly as class attributes.
  
  Attributes:
  
      *figs*:
        dictionary of the form {*num*: *manager*, ...}
  
      *_activeQue*:
        list of *managers*, with active one at the end
