Inject

Inject is a type class providing an injection from type A into type B. An injection is a function inj which does not destroy any information: for every b: B there is at most one a: A such that inj(a) = b.

Because of this all injections admit partial inverses prj which pair a value b: B back with a single value a: A.

Since: 1.0
Note: Prior to cats 1.0, Inject handled injection for type constructors. For injection of type constructors, use InjectK.
