public interface CharacterSubstitutionInterface
Used to indicate the cost of character substitution.
Cost should always be in [0.0 .. 1.0]
For example, in an OCR application, cost('o', 'a') could be 0.4
In a checkspelling application, cost('u', 'i') could be 0.4 because these are
next to each other on the keyboard...
