DESCRIPTION:Often we define functors F where each object F(A) satisfies a u
 niversal property\; these could be products\, limits\, colimits\, (co)ends
 \, (co)free objects\, kan extensions\, exponential objects... Usually\, ex
 istence and uniqueness of the mediating morphisms allow you to define the 
 functorial action and verify functoriality\, respectively. But as these co
 nstructions get more complicated\, the diagram-chasing gets more and more 
 tedious\, and one gets the feeling that there should be some universal the
 orem giving functoriality for free.\n\nThis talk will show such a silver b
 ullet _does_ exist! In these situations of a **parametrised family of univ
 ersal properties** there is an economical\, "maximally lazy" way to define
  your functors on objects\, and deduce the action on morphisms.
