Carbohydrates: Adding TautomerizeAnomerMover
This merge introduces a new sugar-specific `Mover` that will convert a random reducing-end saccharide residue into its anomer; that is, this `Mover` will swap an α-sugar into a β-sugar and _vice versa_. Reducing-end sugars tautomerize readily in aqueous solutions between the two isomeric forms, and it is generally not certain which form is preferred (if any) in sugar-binding proteins.
All tests pass.
