//this is just a demo routine.
// in reality, doing it this way wuuld prevent , you from starting
// "nachocalendars"
//that had different locales, under the same instance.
//this gould be gotten round by generating a hashmap eachtime a different
// locale
//was called.
// but also there in no need to keep creating instances of "dateformatsymbols"
//one would do, for each used locale.
//originally I was passing in a simple date format, which was a lot cleaner.
//but unfortunatly there was no way to recover the locale from it.
//this was needed to get the correct "dateformatsymbols"
//it was either a re-write of most of the classes, or this minor botch.
