Introduction

 
Creation Functions

      Creation of Coproducts
            cop< S1, S2, ..., Sk > : Str, Str, ... -> Cop, [ Map ]

      Creation of Coproduct Elements
            m(e) : Map, Elt -> CopElt
            C ! e : Cop, Elt -> CopElt

 
Accessing Functions
      Injections(C) : Cop -> [ Map ]
      # C : Cop -> RngIntElt
      Constituent(C, i) : Cop, RngIntElt -> Str
      Index(x) : CopElt -> RngIntElt

 
Retrieve
      Retrieve(x) : CopElt -> Elt
      Example Cop_cop (H15E1)

 
Flattening
      Flat(C) : Cop -> Cop

 
Universal Map
      UniversalMap(C, S, [ n1, ..., nm ]) : Cop, Str, [ Map ] -> Map
