Add capability / conversion of lattice array in solution objects directly to amino acid outputs.

[Will-Raymond]

Add a function to solution objects that directly converts the ribosomal movements to amino acid outputs. This is useful for sequences that span multiple frames or have error potentials. However, with the current model maker, sequences that allow crossing ribosomal shunts will not have resolvable amino acid outputs. This should be included as a warning to the user if these types of reactions are detected.
