This encapsulates the logic for turning an acceptable preset name into the absolute path for that preset. It can be used to preprocess a presets list to map each preset to its absolute path, which is necessary if `babel.transform` is going to be executed on a file outside the directory subtree where the presets are installed. This adds a getPossiblePresetNames helper encapsulating the logic for what preset names we should try to resolve, and the resolvePreset method just calls this helper and actually resolves them.
