This change renames directories in preparation for the great package
rename. The repository is now in a broken state because the code
itself hasn't been updated. However this should ensure that git
correctly preserves history for each file.

+/**
+ * Combined converter and validator class for transition list JCommander argument strings.
+ * <p>
+ * These strings have the form {@code <DateTime>=<T-str>,[<DateTime>=<T-str>]*} where
+ * {@code <T-str>} is a string that can be parsed into an instance of some value type {@code T},
+ * and the entire argument represents a series of timed transitions of some property taking on
+ * those values.  This class converts such a string into an ImmutableSortedMap mapping DateTime to
+ * {@code T}.  Validation and conversion share the same logic; validation is just done by attempting
+ * conversion and throwing exceptions if need be.
+ * <p>
+ * Subclasses must implement parseValue() to define how to parse {@code <T-str>} into a {@code T}.
+ *
+ * @param <T> instance value type
