-/**
- * This class provides flexible generation of date format patterns, like "yy-MM-dd". 
- * The user can build up the generator by adding successive patterns. Once that 
- * is done, a query can be made using a "skeleton", which is a pattern which just
- * includes the desired fields and lengths. The generator will return the "best fit" 
- * pattern corresponding to that skeleton.
- * <p>The main method people will use is getBestPattern(String skeleton),
- * since normally this class is pre-built with data from a particular locale. 
- * However, generators can be built directly from other data as well.
- * <p><i>Issue: may be useful to also have a function that returns the list of 
- * fields in a pattern, in order, since we have that internally.
- * That would be useful for getting the UI order of field elements.</i>
