// This calculates the Sigma, Delta, Pi adjunctions for a functor F from | |
// the schema for 2 arrow quivers to 3 arrow quivers on a simple instance | |
// see https://www.categoricaldata.net/ . | |
// ie it shows two translations of a directed graph to a RDF like directed | |
// graph. Sigma just gives each arrow a type, Pi duplicates the graph as | |
// many times as their are nodes and for all the arrows in one of the duplicated | |
// graphs assigns it one of the nodes. | |
